Well, I'm OLD, eyes don't work as good as they used too, I'm DUMB, Just learn from looking at the funny papers, AND I AM AN OKIE, California Guys hate us!!!, but...I can't see the damage all that well in the pic soooo, unless you can see and feel fiberglass strands in the area, then all that's required is Gelcoat paste. (Gelcoat and Cabosil) until its like Creamy Peanut Butter. Do a little feathering with a Dremel, clean well with Acetone and then spread the paste in leaving it HIGH so you can sand and shape when its cured. Once you have the materials in place it's a Maximum 30 minute fix and a 45 minute cure time then 30 minutes of sanding and fairing. Just and OLD DUMB OKIES opinion.
