Step 1
Cover undamaged areas of the hull close to the area to be repaired with newspaper. Mask the edges with tape. Use the rotary tool and a pointed grinding bit to dig out the damaged gelcoat. Bevel the edges around the damaged area and grind away the damaged part down to the fiberglass. Be careful not to gouge the fiberglass.
Step 2
Roughen the surface in and around the chip or dent with 80-grit sandpaper to give the gelcoat a rough surface to adhere to. Blow out the dust from the repair area and blot it clean with acetone. Allow the damaged area to dry thoroughly.
Step 3
Mix a small amount of gelcoat in your mixing container according to manufacturer's directions. Add color tint solutions in the proportions and shades suggested by the color matching chart that comes with the tint colors.
Step 4
Add the MEKP catalyst as directed. Be sure to get the catalyst proportions right. Too much will prevent the gelcoat from hardening and create air bubbles. Too little can increase drying time.
Step 5
Fill the damaged area with about 25 percent more gelcoat than you need, to allow for shrinkage. Allow the gelcoat to cover slightly outside the repair area so that all the edges are fully covered. Pop any air bubbles that form with a sharp tool or knife point.
Step 6
Wait at least four hours for the gelcoat to harden. Meanwhile clean up any mess with acetone and paper towels. Allow the repair to cure overnight before sanding.
Step 7
Wipe down the repaired area with acetone and a rag to remove any tackiness. Tape around the edges of the new gelcoat to protect the existing hull. Sand the repaired area with increasingly fine grades of wet/dry sandpaper, starting with 320, then 400 with the orbital sander till you get level with the old hull.
