We found out the hard way that polymer based resins melt right through EPS, so we are going to use epoxy based resin. I have never fiberglassed anything before. I kind of got the picture from Googling that it is kind of like using paper mache, coat the foam in epoxy put the fiberglass cloth over it and paint epoxy into the cloth. Is this the way to do it?
How do I do it? Very, very carefully! Beyond that, I don't know what the heck I'm doing.
Try covering foam with 6 mil plastic, use silicone to glue joints together so there are no leaks and fiberglass over top.
problematic task. do a search into google. this can assist!
