Is it a bad idea to glass a deck with a layer of 7.5oz volan and a layer of 4oz E cloth? Will the difference in weaves effect the way the glass bonds? Which layer should be on the bottom? I’m trying to glass a 6’7" egg from salvaged fiberglass–don’t want to buy anymore if I don’t have to. Thanks!
They are both plain weave e-glass with different sizings. I wouldn’t worry about it.
Volan will soon be gone. That sizing contains heavy metals that will be outlawed in the near future. The glass companies are already designing a “mach” volan in which a silane finish will be tinted green.
