Epoxy Transparency Problem
William Longyard wrote:
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,

How can you tell if it is prepared for polyester or not? Make up a
sample and try to rip if off the substrate?
I ran into an adhesion problem a while ago and I'm now wondering if the
glass I got was prepared for polyester and I didn't know it. After
laminating two layers of 6 oz fabric on my cockpit sole, I was able to
tear the epoxy up with me hands. I was also able to rip the two layers
of glass apart. Maybe this is what happened. Hmm..
