Installation Notes

  1. Clean the application surface with soap and water or isopropyl alcohol to remove any dirt, wax, or oils. Ensure the area is completely dry.
  2. Carefully plan your layout. You can use masking tape to create a straight guideline for the top or bottom of your characters.
  3. Peel a single character from the backing paper, avoiding touching the adhesive side.
  4. Align the character with your guideline and press it firmly onto the surface, starting from the center and smoothing outwards.
  5. Use a squeegee or credit card to rub over the character, ensuring a strong bond and removing any air bubbles.
  6. Repeat the process for all remaining characters in your registration number.
  7. Allow the decals to cure for at least 24 hours before exposing them to heavy water spray or submersion.

Troubleshooting & FAQ

Do these decals meet Coast Guard (USCG) requirements?

Yes, the 3-inch height of these characters meets the federal requirements for boat registration numbers. However, you must also ensure your state's specific requirements for color contrast, spacing, and placement are met.

How do I ensure the decals are applied straight?

For best results, use a strip of masking tape to create a straight horizontal line on your boat's hull. Align the bottom or top of each decal with the edge of the tape as you apply them.

Can these decals be removed?

Yes, they can be removed. Gently warming the decal with a hairdryer will soften the adhesive, allowing you to peel it off. Any remaining residue can typically be cleaned with an adhesive remover or isopropyl alcohol.

What surfaces can I apply these to?

These decals adhere well to most clean, smooth, non-porous surfaces, including fiberglass, gelcoat, painted metal, plastic, and glass. They are not recommended for rough or porous surfaces.

How many registration numbers can I create with one kit?

The kit contains 4 of each letter and number. A standard registration number (e.g., "ST1234AD") uses 8 characters. This kit provides enough characters to create two complete sets of registration numbers for both sides of your vessel, with plenty of extras.

What is the difference between OEM and aftermarket parts?
