Installation Notes
- Clean the application surface thoroughly with soap and water to remove any dirt, wax, or oil. Rinse completely.
- Ensure the surface is completely dry before application.
- Plan your layout. Use masking tape to create a straight guideline for the top or bottom of your decals.
- Measure and mark the spacing for your registration number to ensure it is even.
- Carefully peel each decal from its backing paper, avoiding touching the adhesive.
- Apply the decal to the surface, pressing firmly from the center outwards to prevent air bubbles.
- Use a squeegee or credit card to smooth out any bubbles and ensure a strong bond.
- Allow the adhesive to cure for at least 24 hours before exposing the vessel to water.
Troubleshooting & FAQ
Are these decals compliant with US Coast Guard (USCG) regulations?
Yes, the 3-inch height of these characters meets the standard USCG requirements for boat registration numbers. However, you must also ensure they are placed on the forward half of your vessel and are in a color that contrasts with the hull.
What is the best way to ensure the decals are aligned properly?
We recommend creating a guide using masking tape to establish a straight line. Measure and mark the spacing between characters before application to ensure a clean, professional look.
Can I remove the decals without damaging the boat's surface?
Yes. Gently heat the decals with a hairdryer or heat gun to soften the adhesive, then carefully peel them off. Any remaining residue can typically be removed with an adhesive remover safe for marine finishes.
How long will these decals last in a marine environment?
The 4 mil outdoor vinyl is designed for durability against sun, water, and fuel. With proper application on a clean surface, they should last for several years in a typical marine environment.
What do I do if a decal starts peeling?
Peeling is usually caused by an improperly cleaned surface or a high-pressure water spray hitting the edge. If a decal lifts, try cleaning underneath it with alcohol, letting it dry, and pressing it back down firmly. For best results, replace the individual decal.
Do I need to register my kayak or PWC?
Registration requirements vary by state and are typically required for any motorized vessel, which can include kayaks with trolling motors and all personal watercraft (PWC). Check with your local state boating authority to confirm specific registration rules.
