When I glass a regular poly should I go 2 layers of 4oz around the fin boxes or is one layer ok.When I do an EPS I go 2 layers on the bottom,poly just one.
Teddy, Two layers of glass around the fins boxes minimum. Three in total would be preferable. Personally, I think it’s best to cut a couple of patches that extend about 1.5 - 2.0 inches out from the center. It’s a great system if you just beef up the glass around it a little. Mahalo, Rich
