Troubleshooting & FAQ

What surfaces can I use these stickers on?

These vinyl letters and numbers are designed for any hard, dry, smooth, and clean surface. They are commonly used on boat hulls (fiberglass, aluminum), mailboxes, glass windows, car bodies, and plastic or metal signs.

How do I ensure the letters stick properly?

For maximum adhesion, thoroughly clean the surface with soap and water or rubbing alcohol to remove any dirt, wax, or oils. Ensure the surface is completely dry before application. Apply firm, even pressure across the entire sticker.

Are the letters reusable?

No, they are designed for a single, permanent application to ensure a strong, waterproof bond that lasts in outdoor conditions.

How resistant are they to weather and fading?

The stickers are manufactured from durable, weatherproof vinyl that is UV, fade, and scratch resistant, ensuring they remain legible and vibrant even with long-term exposure to sun and water.

Can I use these for my boat's registration numbers?

Yes, the 3-inch height, clear block font, and high-contrast colors are designed to meet typical requirements for boat registration numbers. However, always verify your local or state-specific marine regulations to ensure full compliance.

What is the distribution of letters and numbers in the set?

The package contains a comprehensive assortment across 144 pieces suitable for most common words and number sequences. The exact count for each individual character is not specified.
