Gel coat
Joe, I've been trying to apply Gel to my O'Day for years and even with the right color mixture, it still never comes out looking good. The biggest problem with Gel coat is; that it has to cure from the inside out. This means that you need to apply either a wax base mold release liquid with a spray gun, or seal the Gel coat with wax paper or cellophane and tape the edges with tape. Then it has to be smoothed out with a putty knife. When it's dry, I would hit it with a super fine wet or dry 600 or 800 grit sandpaper to make it blend in with the existing color. I've tried those Pre-Val spray cans for the Gel coat and the Mold release wax, and it still doesn't come out good. So, I've come to the conclusion that if there's a guy out there that has the equipment and does great work, it's far better to have him do it and spare myself the headache of trying in myself. One of my friends had this guy at a local boatyard do a repair plus Gel coat, and it came out so good, that you couldn't tell where the repair was made. By the same token; another one of my friends had this guy come down and do a repair, and it came out looking terrible, like a neophyte like me had done the work. So, if you want to give it try, go ahead, but I've been trying for years and never got good results. In fact, I've even thought about doing my boat over with Awl Grip. It would probably come out better. Check around, and find out who does the best work in your area. Ask to see his work before you use him. As for me though,-- the old saying is; "Been there, done that."
