Yeah for the gaunts thats fine, you could use bondoglass if you want the fiberglass in it, but like A'den said just resin and bondo is good enough... You aren't gonna be stepping on your gaunts for support are ya'?A resin coat would probably be fine, then with a coat of bondo over it for general smoothness and such...should be fine.
That was me...if you use alan's WOF temps, you can cut a hole in the underside of the gaunt and slush some resin around in the inside...works well.![]()
