Installation Notes

  1. Prepare Surface: Thoroughly clean the application area with soap and water or rubbing alcohol to remove any dirt, wax, or grease. Ensure the surface is completely dry.
  2. Measure & Align: Use a measuring tape and masking tape to create a straight guideline for applying the decals. Ensure proper spacing to meet local regulations.
  3. Peel & Apply: Carefully peel each decal from its backing. Avoid touching the adhesive. Position the decal along your guideline and press down firmly from the center outwards.
  4. Smooth Decal: Use a squeegee, credit card, or flat edge to smooth out the decal and remove any air bubbles.
  5. Cure: Allow the decals at least 24 hours to cure and bond to the surface before exposing the vessel to water.

Troubleshooting & FAQ

Do these decals meet USCG requirements?

Yes, the 3-inch height of these decals meets the minimum size requirements for registration numbers as set by the United States Coast Guard (USCG).

What surfaces can I apply these to?

These decals are designed for smooth, non-porous surfaces such as fiberglass, gelcoat, and painted metal. They are suitable for boats, personal watercraft (jet skis, Sea-Doo), and kayaks. Application on textured surfaces may yield varied results.

Are the decals resistant to fuel, salt, and sun?

Yes. They are manufactured from marine-grade vinyl and feature a clear UV coating that provides protection against fuel, oil, saltwater, fading from sun exposure, and scratches.

How many of each character are included?

The package contains four complete sets of the alphabet (A-Z) and numbers (0-9), for a total of 144 individual decals. This provides enough characters to complete your registration number with spares.

Can I remove the decals later?

While designed for permanent application, the decals can be removed. Gently heating the decal with a hairdryer or heat gun will soften the adhesive, allowing you to peel it off. Any remaining residue can be cleaned with an adhesive remover.
