Re: small hole in boat
Yep, Use a RO sander with 60 grit and sand the area around the hole so you have and area about 3" in diameter. Try and feather it in towards to hole so the edges of the hole are almost a razors edge thin. Cut some 1.5 oz CSM about 1/2" larger than the hole and then another piece 1" larger than the first. The cut a piece of 1708 Biaxial 1 " larger than the last piece of Csm and finally one more piece of CSM 1" larger than the 1708. Mix up some Polyester resin and Hardener, wet out the smallest patch first and apply it over the hole and then apply all the rest in succession. Take care to not get any air bubbles under any of the patches. Use an old "Chip Brush" to do the work an smooth it all out. 30 minutes it will be ready to Sand. You can use some 3M premium marine filler to fill in any low spots or irregularites and then use a gelcoat paste to coat it a blend in the color or Paint it .
