Dear friends,

I have a question:
my boat has a high level of moisture in the hull but I don't see blisters.
Somebody saya that in this situation is better dont do any treatment, any
epoxy barrier coat, because it can be even more dangereuse.
Others say to apply a thick epoxy barrier to decrease the volume of water
coming in the grp.
I'm a bit confused. What is your opinion and suggestion?

Fair wind.

How old is it?

Lay it up for a year in a sealed, dehumidified hothouse with plastic
on the floor, then use a barrier coat. You will have a year of
heating / cooling and dehumidifying bills to pay and time to check
out all barrier coat options.

If you want it right away, use a fisherman's copper bottom and launch
it. No problems, no action. We don't fix what ain't broke, or
obviously breaking. A stitch in time may save nine.

My 40 year old fiberglass Tyler 29 sailed in fresh water has no
blisters, wintering ashore, using only flaking cheap co-op bottom
paint. Salt water mileage may vary. My 30 year old (then, 1990)
Hinterholler 28 had no real blisters, only a few tiny warts, don't
know where it was sailed, aside from Lake Ontario. I guess the 60's
were a good decade for polyester resin.

The epoxy sales club may now chime in.
