How to Repair Scratches on a WaveRunner

Explore America's Campgrounds

When WaveRunners are out of the water, they can easily become scratched during transportation and storage. These scratches are easily removed if you know the correct technique, and have a little bit of patience. The repair process requires a lot of waiting time while the filler and paint dry between steps. But the finished results are well worth the wait and effort. The damaged areas look like new, and no one sees the damaged areas on the repaired WaveRunner.

Items you will need

  • 2 soft rags

  • Bucket

  • Water

  • Liquid detergent

  • Epoxy filler

  • 2 1-inch square piece of cardboard

  • Toothpick

  • 80 grit and 320 grit sandpaper

  • Sprayable sealant

  • Matching touch up paint

  • Urethane clear coat touch up paint

Fill a bucket with cool soapy water, and wash the area with the scratches with a soft rag. Make sure you get out any dirt, algae or debris. Dry the area thoroughly with the dry rag.

Fill any deep scratches with an epoxy filler. Mix the filler according to the manufacturer's instructions as each epoxy filler is slightly different. Use the toothpick or piece of cardboard for filling in the scratch, and let it dry thoroughly. Check the manufacturer's instructions on the epoxy filler for the appropriate drying time.

Sand the scratched area by hand using 80 grit sand paper. Once you remove any ridges or rough areas, switch to 320 grit sandpaper. Sand over the whole area again with the 320 grit sandpaper, so it removes any scratches or rough spots.

Spray a coating of sealant across the sanded area. This seals the epoxy, and makes the area more waterproof.

Paint a little bit of the touch-up paint on a piece of cardboard, and let it dry. Hold it against the WaveRunner, and make sure the paint matches. If it isn't a good match, go back to the place where you purchased the WaveRunner, and find a closer match.

Hold the touch up paint spray can 12 inches away from the damaged area, and lightly spray the paint. Put on one thin coat of paint on the damaged area. Let it dry for at least 20 minutes. Add two more coats of paint following the same procedure.

Lit it dry overnight. Sand across the painted area with 600 grit sandpaper. Wipe the sanded area with a damp cloth, and let it dry.

Coat the damaged area with three coats of clear urethane spray touch up paint. Make sure you keep the can 12 inches away from the WaveRunner, and let it dry between layers. Let it dry for 24 hours before putting it in the water.


  • Most places that sell WaveRunners have all of the basic colors of touch up paint and clear coat available at the store.
