Installation Guide
For a professional-looking and durable application, follow these steps:
-
Prepare Surface: Thoroughly clean and dry the application area to remove any wax, dirt, or oils.
-
Plan Layout: Measure and plan your character layout to ensure it meets your state's spacing and placement requirements. A level or masking tape can help create a straight line.
-
Peel: Carefully peel the backing from each individual character.
-
Apply: Position the decal on the vessel and press down firmly, starting from the center and moving outwards to remove any air bubbles.
-
Adhere: Rub the decal to ensure it is fully adhered to the surface.
Note: Some brands may offer "Custom Build" kits where the registration numbers come pre-spaced on a single sheet with an application pre-mask for a simpler one-piece installation.
Troubleshooting & FAQ
How do I ensure these decals meet my state's legal requirements?
These decals are 3 inches in height, which meets the minimum U.S. Coast Guard standard for most recreational vessels. However, you must verify and follow your specific state's regulations regarding color contrast, spacing, and placement of registration numbers.
What is the best way to apply these for a bubble-free finish?
Start with a perfectly clean and dry surface. When applying, press down from the center of the decal and smooth your way outward. A squeegee or credit card can help to press out any stubborn air bubbles before the adhesive fully cures.
Can I remove these decals later?
These decals use a strong, permanent waterproof adhesive intended for long-term use. Removal is possible but may require tools like a heat gun and an adhesive remover. They are not designed for repositioning or easy removal.
