When you begin to see the scratch disappear, bump up to 320 grit. When 90 percent of the scratch is gone, move up to 400 or 600 grit and begin wet-sanding, working your way up to 1000-grit. When you use 400 grit or higher, be sure to wet sand. Always keep the sandpaper clean with nice fresh water and be cautious not to remove too much gelcoat.

Once the surface is clean and dry, mark off the repair area with masking tape. Next, gouge out small, narrow cracks (and scratches that are too deep to remove with rubbing compound) until they are wide enough to fill with gelcoat paste. A miniature grinding tool like a Dremel is ideal, but the sharp point of a can opener will work, too.

Gelcoat resin is too thin to fill a scratch and gelcoat paste is too thick. Instead of penetrating scratches, gelcoat paste will bridge them, leaving a void in the repair. To get a permanent repair, draw the corner of a scraper or screwdriver down the scratch to open it into a wide V.

Use a small wood or plastic putty knife to spread the gelcoat smoothly over the gelcoat repair. You should have about 10 to 15 minutes of working time after adding the catalyst before it starts to harden and is no longer fluid. Fill the repair slightly higher than the surrounding surface to allow for sanding.

How to Repair a Boat's Gelcoat If the problem is a minor scuff or scratch, try wet-sanding and see if that makes it disappear. Assuming wet-sanding doesn’t cut it, get a gelcoat repair kit with gelcoat paste and hardener, pigments (if the gelcoat is colored), a plastic spreader or putty knife, and release film.

Mix up your gelcoat, the pigments, and any other coloring elements in the mixing cups. Stir them with your sticks, making sure to wear both your dust mask and latex gloves during the process. You want to avoid breathing in the fumes from Gelcoat or getting it on your skin. Step 2: Smoothing the Gouge

Begin by sanding around the area and the scratch with 320-grit paper. Again, be cautious not to remove too much material. After sanding, use a Dremel tool to clean out the gouge a bit, then feather the edges of the scratch with 180-grit. This helps the gelcoat blend in and helps hide the edges of the filled scratch.
