Re: Stus-List Hull paint pressure wash chips

[Dennis C. via CnC-List]

I uploaded some pics of Touche's gelcoat pox here:

https://drive.google.com/open?id=0B_sb5TfIENvsY2xPRW9XNUhLczg

A couple of the pics were taken before the bottom paint was removed but the
pox is still visible.  Pressure washing revealed many more.  See "Gelcoat
pox close up2".  I think this pic was after I ground them out.  They were
all within 6 inches or so of the waterline.

As I stated earlier, the fix was to grind them out with a cone shaped
grinding stone in a right angle die grinder.  I seem to recall I got that
technique from Wally.  Once ground out, the holes were washed thoroughly
with water, then an acetone wash then filled with 3M Premium Filler.
AwlFair is also a good choice.  The filler was wiped on with a plastic
spreader in multiple directions to ensure good filling.  See "Gelcoat Pox
Filled".  Then the area was sanded.  All this was prior to a barrier coat
application.

This work was done in 2007.  They have not reappeared.

Steve,

Would be nice to see a picture or two of the "paint chips" which you 
subsequently refer to as holes in your posting.  I would be concerned 
that they could be a result of pox.  Should that be the case, a more 
extensive repair is necessary.  When I redid the bottom of my C 36, I 
examined it for pox closely.  I found none, but still decided to sand 
blast it in the fall and let it dry over the winter.  I then applied 4 
to 5 coats of Interlux 2000, followed by VC 17 bottom paint.  It has 
held up very nicely since that time.  I only apply the VC 17 each year 
to keep the Zebra Muscles off the bottom.  If you have to repair holes 
all over the bottom, you may want to use West System Epoxy.  It takes a 
while and it is work, but when it is done and then coated with Interlux 
2000, followed by a bottom paint, you should have no problems in the 
future.  I am sure other from you area may have more pertinent advice.  
I am in fresh water on Lake Michigan.

Subject: Stus-List Hull paint pressure wash chips

One result of many years of barnicle build up, followed by scraping and 
aggressive pressure washing is that a number of paint "chips" were 
ripped out right down to the fibreglass or lead substrate on the 
new-to-me-but-old-and-neglected C that I am attempting to renovate. 
My intent for the time being is to remove the remaining barnacle 
plates, lightly sand the existing ablative, and replace it with more of 
the same. That said, I think it would be wise to do something about 
these holes, and that a few tubes of spot putty might do the trick. The 
main question I have is should I use some sort of primer first, and 
what product is likely to work?

Ditto AwlFair.  Good stuff.  I just had 3M Premium Filler on hand.

Re: Stus-List Hull paint pressure wash chips

Steve,

My hull came with hundreds of those little holes. At or near the waterline. A 
PO had the original bottom stripped off and replaced with glass and epoxy up to 
the waterline so any in that area were fixed. I just lived with those buggers 
until last year when the hull was repainted.

Like Dennis said, they were just ground out a bit, cleaned and filled, in my 
case with Awlfair, sanded smooth and painted over.

Best,

Steve,

Are these small pea sized nearly round shallow holes near the water line?

If so, they're what I call gelcoat pox.  Touche' had hundreds.  I've heard
reports of other C's with them.

I ground mine out with an air powered right angle die grinder with a cone
shaped grinding stone.  Took a couple hours but the die grinder is the
right tool.  Dremel just didn't work.

After grinding, apply acetone wash, fill with 3M Premium Filler, sand
smooth and paint.
