You can get color matched gelcoat by manufacturer from Mini-craft of Florida. Just remember that your gelcoat may have faded so the color may not be perfect until the repair ages. to repair, back the underside of the holes with F/G mat or with silver metal duct tape ( not the gray duck tape everybody uses ). Then fill the holes with a good polyester marine fillers, leaving 2 or 3 mms deep for the gelcoat. mix the gelcoat and wax and fill leaving a slight "crown" over the repair. When dry, start sanding. First, rub a little black lacquer ( sprayed over an acetone wet rag to thin it) over the repair, and, using a sanding block sand it level. For small repairs I would start with 100 grit. When the lacquer is gone and the repair looks level, switch to 200 grit. Rub lacquer over repair and sand just until the lacquer disappears. switch to 300 or 400 grit and repeat the drill. switch to 600, 1000, 2000, each time repeating the process. use wet/dry paper and lubricate repair with water while sanding. Most importantly, don't be too aggressive with the initial sanding. You want to level the repair with the surrounding gelcoat, not remove the surrounding gelcoat. using the lacquer will help you gauge only how much you need to remove between sandings. Finally, polish the repair with a machine and fine compound or polish. If you.ve followed these instructions the repair should look good. It's worked well for me. Remember, this isn't rocket science. just take your time, follow the mixing instructions for your filler and gelcoat, and you should be fine. good luck with your repairs.
