Jet Skis are somewhat like miniature boats, and have to withstand the wear and tear of any marine vehicle. As a result, you may notice that the finish on your Jet Ski has begun to wear away over time. You also may simply wish to change the color of your Jet Ski. In either case, the best solution is to paint it. Painting fiberglass is somewhat challenging, as it takes a lot of preparation, but the end result is likely one you will be proud of.

Items you will need

  • Automotive or marine paint
  • Automotive or marine primer
  • Sandpaper (400 grit)
  • Paint sprayer or brush
  • Masking tape
  • Newspaper
  • Tack cloth
  • Air compressor (optional)
Step 1

Remove as much hardware as possible from the fiberglass areas you are planning to paint. Mask any areas you do not wish to paint with newspaper and masking tape. This should include any hardware that you can't easily remove. Make sure all of the areas to be painted are still showing.

Step 2

Sand the surface of the fiberglass with 400-grit sandpaper until any wax and gloss is removed. The surface should be slightly rough with no gloss.

Step 3

Blow away the sanding dust or use an air compressor to blow it away, then wipe the entire surface down with a tack cloth to ensure all of the dust has been removed.

Step 4

Apply a layer of primer to the fiberglass with a paint sprayer or a brush. A paint sprayer is recommended for a smoother finish. Use long, even strokes to avoid any bumps in the primer. Allow drying time before painting based on the label of the primer.

Step 5

Apply a layer of paint to the fiberglass with a paint sprayer or a brush. Use long, even strokes to avoid bumps once the paint dries. Allow the proper amount of drying time based on the recommendations on the label. You may wish to add multiple layers of paint for a more even finish.

Step 6

Remove the masking tape and newspaper once the paint is completely dry. Replace all hardware that was removed previously.

Tips & Warnings

  • Add a coat of clear automotive paint for a more glossy finish.
  • Always wear a breathing mask and work in a ventilated area when painting, especially when using a paint sprayer.
