I started sanding the drains around my hatches to have the deck repainted and I found some small voids underneath the gel. It looks like there were air bubbles or the resin didn't fully penetrate. Either way I sanded them out and I was going to use a two part epoxy, PC-11 to fill them, then sand them smooth for repainting.. Thats what the marine store recommended. Does this sound like the correct method? or should I use another type of epxoy. Also how much gel do I have to sand off. Just so the surface is smooth or do I have to go all the way down the underlying glass? Thanks for the help guys.
