I was sitting there at work today cutting out fiberglass panels and started to wonder if it would make a better wall for my next box instead of plywood painted white. I can cut them to whatever size I need and they are about 1/8'' thick. It wouldn't be as sturdy but it has a glossy white gelcoat that just blinds you in the sun. I can only think that maybe it might not be thick enough and cause it to be cold..but my lights i would think would make it warm enough..I don't know sorry for rambling I was just wondering if anyone thinks this is a good idea?
