RE: [bolger] Fiberglass over plywood repair question
Bill,
I recommend removing the loose cloth and replacing it with new fiberglass
and epoxy. You will have a much better result.

Bill, I am engaged in a similar but (unfortunately)
larger scale problem with a plywood deck. If the
polyester bond is starting to fail you will be best
off if you re-glass with epoxy, because the poor bond
will allow water to wick in, where it can't dry and
can start rot. The poly/glass tape comes off pretty
readily with a heat gun, in my experience. Good luck.

I'll second this recommendation too. Adding only; make sure that
your exposed wood surfaces all are dry and nicely sanded before
applying the new "fix",pre-coat the exposed wood(especially the
plywood) prior to 'glassing and finally,work hard at getting a
nice,feather edged,'glass overlap so that you have a minimum of
fairing to do before painting.
With any kind of luck your repair will be perfectly invisible and
you very proud of your handywork :-)

For a longer lasting repair you should cut away all the delaminated poly/glass then replace it with new epoxy/glass. Naturally this will be a lot more work than the quick fix.
Using epoxy to glue the poly/glass layer onto the wood where it has delaminated might work too, and it would be faster and cheaper and easier.
It really depends upon how much work you want to put into a repair like this, and whether or not the location of the damage seems like it may pose a safety hazard or if it is instead just a cosmetic issue.

I've just acquired a plywood boat that has been fiberglassed with some
sort of polyester/vinylester type resin that doesn't stick to wood as
powerfully as epoxy. The bow of the boat at some point rubbed against
a dock enough to abrade through the glass over the stem, and into the stem
a fraction of an inch (it kind of looks like the mahogany stem was
tougher than the fiberglass protecting it). Anyway, on the sides of
the stem the glass has peeled from the wood an inch or so back from
the damage. I'm wondering if the stuff can be restuck to the wood
with epoxy, or if I should just cut/grind/sand away the loose area and
just cover it with a layer of cloth and epoxy. The damage,
incidently, is all above the waterline, and the boat is on its trailer.
