So my son and I tried our first fiberglass repair and failed. It is a learning process I know. If you look at the first two pictures you can see the hole in its original glory. Then we grinded the area and put four layers of chopped matt fiberglass over the hole. Covered it with release fabric and smoothed it out. After curing, we hand sanded it and you can see the area is perfectly smooth now but the crack reappeared. Should I regrind it out and try it again with the biaxial cloth which is thicker? Or fill the crack with expoxy fairing compound? That seems wrong. I don't understand why the crack appeared.
