Hi Brian,
It's not humidity, so maybe the wrong cloth? I'll look into that.

Thanks,

I'm having trouble covering some plywood with fiberglass cloth. The
problem
is that I want to be able to see the wood under the cloth, but the cloth
just doesn't seem to want to get "transparent". I've covered plywood
before
using this method, including a wooden kayak, and it usually comes out
great.
I've been able to sheath the foredeck of the boat successfully, and the
fiberglass "disappears" into the epoxy resin, but for some reason all of a
sudden I'm having problems. It gets about 90% transparent, but stays a
little milky. I've made sure that I lay the cloth onto a wet piece of
plywood, and that I force more epoxy into the weave, but still it looks
only
partially transparent. Ideas?

Thanks,
Bill L.

Off the top guesses:
fiberglass prepared for polyester resin
or
humid day.
