I turned the hulls over and did some sanding today. I didn't forget to use my respirator, but i'm wishing I had worn something other than shorts and a t-shirt. First I took my angle grinder with a 80 grit sanding disk and buzzed off about 1/3" of gelcoat on either side of the damage. This was kind of like using a chainsaw to do surgery, but i can't imagine how long it would have taken without it. Then I took my electric sander with 80 grit and rounded everything off. I'm concerned that everything is too smooth now tho, will fiberglass stick if it's not rough enough? I had purchased 3" glass tape, but even after taking off some gelcoat, I only have 2-2.5" of damage to repair. Which brings me to my next question, should I fold the tape in half, or cut it in half and lay it down one layer at a time? or should I buy 2" tape? I'm thinking that, after laying down 4 or 5 layers, I'm going to thicken some resin with those microbeads or something else and fill the areas needed to make it the original shape. Sand. Gelcoat. Sand. Sand. Polish.
