Troubleshooting & FAQ

How do I ensure the decals stick properly?

Clean both your hands and the application surface thoroughly before starting. The area must be completely free of dirt, oil, and wax for proper adhesion. Use a straight edge to create a guide line and press each decal firmly during application.

Are these decals compliant with US Coast Guard regulations?

Yes, the 3-inch height meets the minimum size requirements for boat registration numbers as specified by the U.S. Coast Guard. Federal regulations also require the numbers to be placed on the forward half of the vessel in a color that contrasts with the hull.

What makes these decals suitable for a marine environment?

The decals are made from high-quality vinyl with a protective UV coating. This makes them waterproof, sunproof, and resistant to fuel, fading, and scratches, ensuring they withstand harsh marine conditions.

How many registration numbers can I create with one kit?

Each kit includes four complete sets of A-Z letters and 0-9 numbers, which is typically enough to create registration numbers for at least two vessels (both port and starboard sides), with plenty of spares.

Will the colors fade over time?

The decals are treated with a UV-resistant coating specifically to protect against sun exposure and prevent fading, ensuring the color remains vibrant.

Can I remove the decals without damaging the boat's surface?

Yes. To remove, gently heat the decal with a hairdryer to soften the adhesive. Then, you can peel it off. Any remaining residue can typically be cleaned with an adhesive remover that is safe for your boat's gelcoat or paint.
