No I didn't do any wet sanding, just buff, polish, and wax. There are some very helpful people on this forum that should be able to give you some good advise. I had never even used a buffer before and they pretty much told me step by step, what products to use, ect. Somebody must have clear coated your boat at one time, cause as far as I know gelcoat, if it's done right, won't peel.
