Installation Notes
- Clean the application surface thoroughly with soap and water or rubbing alcohol. Ensure it is completely dry and smooth.
- Position each decal to ensure it meets local and USCG spacing and placement requirements. Use masking tape to create a temporary alignment guide.
- Carefully peel the backing paper away from an individual letter or number.
- Apply the decal to the surface, starting from one edge and smoothing it out with a squeegee or credit card to remove air bubbles.
- Press firmly across the entire decal to ensure strong adhesion.
- Allow 24-48 hours for the adhesive to fully cure before exposing the vessel to water.
Troubleshooting & FAQ
How do I ensure my registration numbers are compliant?
These 3-inch block-style characters meet US Coast Guard (USCG) guidelines. To remain compliant, attach them to both sides of the forward half of your vessel in a color that contrasts with the background, ensuring they are clearly legible.
What is the best way to apply these decals for longevity?
For best results, apply to a clean, smooth, and dry surface when the temperature is moderate (ideally above 50°F or 10°C). Use a squeegee to press out any air bubbles and allow the adhesive to cure for 24–48 hours before water exposure.
Can these decals be removed once applied?
The permanent marine-grade adhesive is designed for long-term durability. If removal is necessary, gentle heating with a hairdryer can help soften the adhesive, allowing the decal to be peeled off. Any remaining residue can be cleaned with an appropriate adhesive remover.
How long will the decals last on my boat?
Made from premium 4 mil outdoor vinyl with UV-resistant ink, these decals are engineered to resist fading, curling, and chemical deterioration for several seasons under normal marine conditions.
What are the signs that my registration decals need replacing?
Inspect your decals periodically. You should replace them if you notice significant fading, peeling or curling at the edges, cracking, or any damage that reduces their legibility from a distance.
