Hey all, I'm just finishing up my second board and am a little concerned because the board seems real soft. Like I didn't add enough glass. It's made out of some jobsite polyiso foam with a 6+4 oz deck and bottom glassed with polyester resin. I built another board out of the same foam with the same glass schedule, but used epoxy resin and the board has held up fine for the last 6 months.
The board has been glassed, hotcoated and sanded. I'm getting ready to gloss it and polish, but am feeling an extra layer of glass couldn't hurt. Will a second fill coat add any strenght? or should I suck it up and add more glass. The board is 5-10, 2.5, 20.5 fish type thing and quite light compared to my previous effort.
I know the foam I used is sh1t , but it was free and if it came out like crap I wouldn't feel bad.
Thanks, belch
