Sebastian - 20 Apr 2006 04:31 GMT
Hi

I have a 26 year old Mirage 27 sailing boat, beautiful condition inside,
however the hull has become dull, looking tired and her age.  I would like
to clean and bring back the shine.  I have heard both pro's and con's of
silicon polish.

Can anyone advise a good fiberglass cleaner, and resolution to the "dull
hull" syndrome.

I need to apply anti-fouling this year, should I use the cleaner below the
water-line before applying the anti-fouling.

Thanks.

I posted the following respone to a similar question on sailnet.net the
other day to the same question:

First look at the gelcoat with a strong magnifying glass or pocket
microscope (Radio Shack). If you see NO 'alligatoring', then the
gelcoat can be wet sanded and powerbuffed back to the 'original' shine
and brilliance.
1. wash the surface with a STRONG caustic detergent ... from a
janatorial supply, then use oxalic acid (wood bleach -- from a paint
store) to remove old dead wax, iron and tannin stains. Dont MIX
detergent and oxalic !!!! rinse in between the two. Wear gloves when
using oxalic as it quickly absorbs through you skin and can damage your
kidneys.

2. Flat sand the gelcoat with 1000--> 1500 -->2000 grit wet and dry
sandpaper using a few drops of dishwashing detergent in a few gallons
of water. Use a rubber sanding block. Sand away until the surface is
flat. Most gelcoat is quite thick .... but stop sanding immediately
when you see the matting layer of fiberglass under layer showing
through .... if you do its time to paint. If not, proceed to 2. The
object is to remove the oxidized outter layer of gelcoat and produce a
FLAT surface ... use the pocket microscope if you have one.

3. Get a high speed autobody power polisher (varibale speed 1000-3000
rpm), 3M foam polishing pads, Coarse Fiberglass rubbing compound, 1000
grit auto body shop compound, 3M finesse it, 3M Perfect polishing
compount, Collinite Fleetwax.

4. Begin with a fresh foam pad (Never mix pads and grits). In a 2ft. by
2 ft. surface apply coarse rubbing compound then do the 2ft. x 2 ft.
square with a foam pad, move to the next 2X2 square until the whole
boat is completed, Then do the same with 1300 grit - whole boat, then
Finesse-it, then Perfect-it. Keep the buffer moving at all times, be
very careful and dont 'burn through' sharp corners. Power buffing can
remove a LOT of gelcoat, so use a 'light touch' .. and keep the buffer
moving so you dont 'overheat' the surface. The speed of the polisher is
what does the work not the pressure. By the time you get to the
Finesse-it the hull should be back to NEW condition shine wise.
Perfect-it with give the deep shine.
You must wax immediately to fill the 'pores' of the gelcoat. Use a
clean bare hand, some water and the paste collinite and rub by hand
until the wax begins to shine, then add about a 10¢ size spread over
the 2X2 and powerbuff. Push the wax INTO the pores of gel ... dont just
smear it across it - this will seal the pores and will retard
oxidation.

99% of the time the above process will restore an old faded hull back
to NEW condition. Its also the same process that is used to powerbuff a
NEW hull when its pulled from its mold. Rewax at about 6 months and
every 12 thereafter as a minimum. Every 2-3 years STRIP the old dead
wax with a caustic detergent, light powerbuff with Perfect-it and
rewax. .... This should keep the boat looking like new for the next 30
years.
You may want to fill in gouges, etc. with new gelcoat before you
powerbuff.

Beware snake oil: acrylic coating 'wipe on' coatings. They look good
for a season or two but ultimately fail and have to be removed (when
they will look like a severe skin disease). The acrylic removal is a
PITA and is ultimately more harmful than the above powerbuffing
method.In article <FgD1g.40957$7a.16136@pd7tw1no>, Sebastian

You are giving excellent advice. I think that the 3M stuff requires
3200rpm. Read the label and follow the instructions and Rich's
prediction will come true for you.
Keith - 20 Apr 2006 07:51 GMT
The above sounds good, but I'd try just buffing with 3m's brown
compound first, then Finesse-it to see if it brings back the shine you
want. I've brought back some pretty bad hulls that way. I only use
Collinite Fleetwax paste wax as well. Works very well and lasts a long
time. Don't get these compounds at the marine store though... you can
get them for half that price on the web. The place I get mine is:

Most auto-restorers use Farecla or something similar, applied with a
man-sized electric polisher.
This will bring up the bare gelcoat prior to polishing with whatever takes
your fancy, it's hard work, but worth it. I wouldn't put wet 'n dry of any
grade anywhere near my gelcoat unless a repair had made this necessary. The
auto-shops are bristling with all manner of polishes at half the price of
so-called boat polish, and there are rather more cars than boats, so take
advantage of the research and development they carry out all the time. Ask a
body shop what they use! I use Mir!

Rich Hampel - 21 Apr 2006 03:58 GMT
I disagree somewhat.
Gelcoat needs a flat surface to shine well, If you start with coarse
compound you wond get the truely flat surface hence the shine wont be
fully developed.     You usually dont need to use much coarse compound
once you get the surface really flat with 2000 grit as coarse compound
is 'probably' in the range of 800-1000 grit.  Wet sanding is a very
FAST way to get a surface Flat .... just like they used to do to get a
lacquer job on a  super-expensive automobile FLAT before the final
polish.

Not my experience or the experience of may who've used them.
Rich Hampel - 21 Apr 2006 03:35 GMT
Yeah sure... and the same folks probably slather their brightwork with
'cetol'.

BTW if you want the acrylic overcoats to look as good as finely buffed
gelcoat, flat sand and buff the acrylic as I described above.  

The 'problem' with these coatings is that eventually have to be removed
when they oxidize and begin to lose adhesion.  Acutally I prefer
urethanacrylic copolymers, especially on teak but with a bit of ferrous
oxide thrown in to retard UV damage.  But still, ****nothing**** looks
as good as freshly buffed gelcoat ... thats the way it comes from the
factory and its really easy to keep that way.  
When I look at a boat for sale, having an acrylic overcoat for me  is a
deal breaker because usually its hiding 'something' and its impossible
to visualize the true condition of the gelcoat.

Total baloney. Mine has not needed "removal" in 8 years. Every spring I wash the
boat to get the dust off and wipe on two maintenance coats. My boat always looks
like it is wet. Always.

Total baloney

If I see a boat with wax that is very shiny, I know that there is probably very
little gelcoat left after the owner has been foolishly grinding it thinner and
thinner every year.

Which product are you using?  Is it something similar to the Poli Glow
that was being discussed here a while back?

BTW I suspect this is one of those situations where there is some
truth to both points of view depending on standards, situation, and
maintenance.  I'm probably going to go to a wipe on coating because my
boat will probably need paint in five years anyway due to PO caused
damage.  Looking at it closely, I think it may be a boat that came out
of the mold with surface problems and had a new gel coat applied
immediately.  Buffing is also something I have to hire out.

When the old gel coat starts getting thin, why not just have
 new gel coat sprayed on and buffed out?  We hit a rock
with our power boat last year and had a 6' x 1" gash
repaired.  As part of the repairs, they resprayed the entire
bottom of the boat with gel coat, sanded it smooth, and then
buffed it out.  The cost on a 21' boat was not prohibitive
($3700 including the fiberglass repairs).

There may be a very good reason to not re-gelcoat, but it
eludes me at the moment.

Gee, extrapolating up for size, that works out to over 1/3 of the
purchase price of our used 32 foot sailboat or, about the price of a
whole new set of sails, complete with the spinnaker we don't have.
Or, I could redo all the rigging, replace the plastic portlights with
metal, add a diesel heater and modify the engine cooling system for
late (freezing nights) season operation and have something left over
for more electronics.

In my world at least, that counts as a reason.

Hi Roger,

I think that you are extrapolating based on the cost of
fixing a 9.14' x 1.5" gash in the bottom of your 32' boat
and _then_ re-gelcoating :)  Note that the gash was entirely
through the fiberglass, not superficial.  The only thing
that kept the boat from sinking was the inner hull.

I have no idea what the cost of spraying, leveling and
buffing the gelcoat would have been by itself, but I doubt
it would have been nearly as much.

How much do you expect to spend to have the hull sanded,
faired, epoxy primed, and then two coats of 2-part epoxy
paint professionally applied?  I'll bet it doesn't come to
much difference by the time you're done, since much of the
labor is in the prep.

But I've been wrong before ;-)

Most of the experts say it isn't cost-effective, particularly with the
durability of the 2-part epoxy paints.

I don't doubt that what you say is true, however...

It seems to me that if the manufacturers could save a bit by
 switching from gel coat to Imron or Awlgrip they would.
Yet the boat manufacturing industry uniformly uses gel coat
instead of paint.

Professional fiberglass repair places also routinely respray
the gel coat and then buff it out.

There is little cost difference between the materials, and
the preparation is similar.

Could it be that the popularity of two-part paints is
because they can be applied more easily by the DIY crowd?

Hi Dave,

Your second mistake is in thinking that I don't know how
boats are built.  I'm not going to tell you what your first
one was--only that you presume a lot without knowing.

Instead of sniping, why don't you share your accumulated
wisdom and point out from your point of view why the
two-part paints are better and cheaper than gel coat.

You could also share your experiences about how you came to
hold those views.

Or not... (waiting)

BTW, have you ever personally painted anything using a
two-part paint such as Awlgrip or Imron?  Epoxy primer?

No need to wait. Go back and read earlier messages in the thread and your
question will be answered.

Meanwhile, I suggest that anyone who says the process of applying a boat's
initial gelcoat is remotely similar to applying paint to the outside of a
hull doesn't know what he's talking about.

I read back through your posts in this thread.  The most
helpful comment you wrote that I found was:

"Most of the experts say it isn't cost effective,

Very helpful.  It suggests that you've read the views of
experts and have a religious belief that coincides with
theirs--whoever they are.

Dave, you are acting like a usenet troll.  You continue to
snipe, and not contribute or answer the questions asked.  I

won't see my posts in the future.  I'm adding your name to

That's not exactly true, Don. If you order a new red or blue C&C 99, they take a
standard gelcoated white hull and PAINT it with awlgrip. I would not be at all
surprised if that is the way the majority of manufacturers do it. (Metalflake
Bass boats aside!)

Interesting.  I went to their website, and see that Awlgrip
is an option for dark hull colors.  I'd like to hear their
rationale.  It is also interesting that they don't offer
Awlgrip in the light hull colors.

http://www.c-cyachts.com/model/model.aspx?UID=4a367bf2-f527-4a33-b144-ed117dc4f1
6f&MUID=2dfa6c71-e233-4175-ae7b-a61eae41d7de


I wonder if they plan to do this for their other models as
well.  The darker gel coat colors do tend to show oxidation
rather badly.

Also, are you sure that they are actually painting over a
white gelcoat?  That seems odd, since scratches would stand
out pretty dramatically and they could just as easily apply
Awlgrip over a color matched gelcoat.

BTW, I'm not putting down the two-part paint systems.  I've
painted with them and they work well.  If sprayed on a well
prepped surface, the finish can be spectacular.  A lot of
people even report good results using DIY methods such as
"rolling and tipping".

My point was that if you are going to go to all the trouble
to prep the hull for painting, and you are set up to spray,
why not spray gel coat.  The material cost is about the
same, and you can spray a much thicker coating that can be
wet sanded and buffed for many years to come.  The downside
is that you may need to wet sand and buff it out after
spraying, and the positive side is that you _can_ wet sand
and buff it out.  For decks, an additional downside to
gelcoating may be that you have to redo all of the patterned
non-skid.  However, I notice that the new Catalinas are
using a texture gun to apply the non-skid instead of using a
mold pattern.

I've been doing a lot of thinking about this lately, because
the deck on our Catalina 27 needs to be redone.  I will
spray it, but the issue is whether to spray gelcoat or
paint.  I have some concerns about the long-term durability
of Awlgrip or any other paint when used as a surface to walk on.

I use poliglow. What Hampel wrote is the standard FUD rant used by boatyard
luddites who are losing income as people switch to PoliGlow and similar
products, and no longer need their services to compund and wax, which is very
labor intensive. I'd be willing to bet that he has no personal experience with
the product at all. If he does, then he is one of the folks who didn't follow
the clear and easy instructions.

The truth in this case is squarely to one side. The simple truth is that
poliglow works exactly as advertised if you follow the simple directions.
Question anyone who claims to have had a poor experience and carefully, and
without exception, they have "improvised" rather than follow the directions.
Forget everything you know about compounding and waxing when you use Poliglow.
If you apply "wax" knowlege to Poliglow, I agree that you will have problems.
I've heard of boatyards charging for untold hours of labor trying to remove
poliglow by compounding it. Pretty stupid, since the manufacturer specifically
tells you that that WILL NOT WORK. The manufacturer has a companion product that
removes poliglow easier than you've ever removed a coat of wax. One other nice
advantage of Poliglow is that unlike wax, which pretty much sits on the surface,
Poliglow fills in the pores of the gelcoat and really seals it to slow down or
stop oxidation.  The air trapped under a coat of wax means your gelcoat
continues to oxidize and will need compounding again and again.

I have recommened Poliglow to a  large number of people over the years and have
never had a single complaint. I've never had anybody go back to wax, either. Not
a single one.
Roger Long - 24 Apr 2006 12:40 GMT
Any reason you couldn't apply Poli Glo in the water at dockside on a
reasonably calm day?

Any hints on stripping the wax put on last year?  The boat sat outside
for six years so there probably isn't much build up aside from the
compound and wax job I had done last spring.

>Any reason you couldn't apply Poli Glo in the water at dockside on a

The issue would be the initial cleaning with Poli-prep, which involves
scrubbing with a scotchbrite pad. If the initial cleaning isn't very
thorough, the poliglow may not adhere well. It's less elbow grease
than compounding, but it's still a bit of work. I supposde it could be
done in the water, but it would be a lot easier on land.

On a boat with an existing installation of Poliglow, doing the annual
maintenance coats while in the water would not be hard at all.

>Any hints on stripping the wax put on last year?  The boat sat outside

By the time you go around the boat with poli-prep and a scotchbrite
pad two or three times, the wax will be gone. It's also important to
get the old compounding residue that is worked into the gelcoat. The
poli-prep and scrubbing is the only answer. It's pretty effective, but
I recommend doing it at least twice to make sure it's REALLY clean.
That's why the folks at Poliglow advise resisting the urge to compound
before applying poliglow. It doesn't gain you any thing, and the
residue has to be completely gone for the poliglow to bond correctly.
I didn't compound my 1986 boat and it always looks like it was just
dipped in a tank of clear lacquer.

I'm active on a Catalina 30 list and quite a few of the participants use
Poliglow and have been quite satisfied with the results. I tried it on that
basis and have been very happy with it so far. I did the initial work (with
the prep solution) with the boat on the hard and have done the maintenance
coats with the boat in the water. Much less work than waxing and it looks
great.

Same thing on the C&C list. A lot of people who already tried it and
liked it have encouraged others to try it, and there hasn't been one
person who didn't like the result. Some of us have been using it for
many years.

That's perhaps a bit too glowing (pun intended.) It does give a nice shiny
surface, but the appearance is a bit less "smooth" than that of a waxed
hull. I like it, particularly its ability to restore faded dark colors, but
it's not for everyone.

It wasn't my opinion, Dave. I was stating a fact. There were
truthfully no people among that group who tried it that reported
disappointment with it.

You seem to be having a comprehension problem. Not being disappointed is not
necessarily the same as believing it's perfect--heaven's answer to a
boat-owner's prayers. I'd say I'm not disappointed with it, but I wouldn't
say it's absolute perfection in all respects.

???

Where did I say it was perfect, Dave. I will say that I do not know of anyone
who wanted anything to do with the old fashioned compounding and waxing routine
again after trying it, though. If it was free for the asking and cleaned the
boat and applied itself without my assistance, it would be perfect. For now it's
closer to perfect than compounding and waxing by a country mile.

I can't seem to find where I said it was perfect.

Your comment about it not being "smooth" was pretty funny, though. Maybe you are
glopping it on too thick. Many thin coats are better and "smoother" than a few
thick ones.  All you "really" said was that wax is dull compared to Poly Glow. I
already knew that. Practical Sailor used scientific measurements to confirm
that. It's a LOT glossier than any wax. Nothing at all to do with whether it is
perfect or not.

I never said anything that could be remotely construed as a statement that it
was perfect. I will say it is a heck of a lot closer to perfect than any
traditional  "compounding & wax" method I have ever used in about 45 years of
owning and working on boats.

Since I use the stuff too, I'm inclined to agree that it's preferable. But
I'd invite anyone intending to use it to take a look at a boat that's had
the polyglo treatment up next to one that's had the conventional compound
and wax treatment, and see which effect you like best, and how much better.
It's one of those things on which reasonable men may differ.

Whatever, Dave. Don't forget the wide disparity in the amount of work involved
as part of  your calculations.

Ya gotta learn to read a bit more carefully. Why do you think I said "and
how much better?"

Maybe you need to write more clearly. This isn't abstract poetry class. My
response stands.

My mistake in assuming a modicum of literacy on the part of the reader.

I already knew that PoliGlow does not recommend their product for use
on boats less than 2 years old. Just to answer your question, I
emailed them to ask what the reason was for that recommendation. They
just replied:

Bill,

Thank you for your inquiry.  PoliGlow is a clear coat that adheres to
the boats surface.  A out-of-the-mold boat has an extremely smooth
surface which the PoliGlow will not adhere to easily.  PoliGlow
requires those microscopic voids in the surface which are caused by
age, exposure to UV, etc. to bond to the surface and function
properly.  PoliGlow is an incredible restoration product.  For a
like-new boat we suggest the following wax:

Hope we answered your question.  Please don't hesitate to follow up if
we
can be of further assistance!

I take it you do not intend to respond to the earlier suggestion that you
have no personal experience with the product?

Coming late to this party, I wonder what is recommended for relatively
new awl-grip.

By relatively new, I mean older than 2 years, which is how long Flying
Pig has been ashore, at a minimum.  That may be significant, as I see
that less than 2-year old gelcoat isn't a good candidate for this
product.  FWIW, the stern and rubrail are both only 1 year old, but the
rest of it is probably 3-5 or maybe more old.

And, I'm wondering how much product would be needed to cover about
400SF or so...

Thanks for any intelligence on the matter.  As we approach the time to
splash, with Lydia's mom available to help dress her out, this is now
on the radar...

Skip,

How is the older Awlgrip looking at this point?

Actually, the correct quote from "Walden" begins "I went to
the woods because..."  Although its is fine to go to sea for
the same reasons.
