I was adding glass to the mounting flange on my hood top today and followed all the steps - grind away the gel coat and about 1/2 of the thickness of the existing flange; cut strips of mat to fit the new area, plus more to span the new and old area; wax the metal form piece; etc. When it came time to mix the resin I added hardner from memory, using the 12 drops per small batch instruction. Problem is the 12 drops is per ounce of resin, and I was doing the six tablespoon measure which needed 1/4 ounce. I figure I was off by at least 1/3, and perhaps 1/2 on hardner. After four hours it is mostly hard with a few tacky spots, but seems to be hardened. Do I need to be concerned with strength? Do I need to do anything special, like let it bake in the sun for a few hours?
