Ok im really sorry as im probablly off topic or at the wrong place to post my question. Ive been building part of my new project sculping insulation ( pink foam and foam card ) ive read a lot on internet about what to use or not but im just wondering if someone have experience on this. Option 1 poly fiberglass = melt the foam, not a good idea. 2 epoxy fiberglass = ive read it is good to go is this right ? 3 coating the foam with something then fiberglass it ? 4 expensive stuff ... Thank you very much and again sorry if im posting this at a wrong place.
