Troubleshooting & FAQ

What surfaces can I use these decals on?

They are intended for hard, smooth, clean, and dry surfaces. Common applications include fiberglass or aluminum boat surfaces, mailboxes, glass windows, vehicle bodies, and plastic or metal signs. Test adhesion on an inconspicuous area when using an unfamiliar surface.

How do I ensure the letters stick properly?

Clean the surface thoroughly to remove dirt, wax, grease, and oils. Soap and water or an appropriate surface cleaner may be used. Allow the surface to dry completely, then apply firm, even pressure across the entire decal.

Are the letters reusable?

No. The decals are intended for single-use application. Removing and repositioning them may reduce adhesion or damage the decal.

How resistant are the decals to weather and fading?

The vinyl is described as waterproof, weather-resistant, UV-resistant, and fade-resistant. Actual service life depends on surface preparation, exposure, temperature, cleaning, and application conditions.

Can I use these for boat registration numbers?

They can be used for boat registration marking applications when the 3-inch character height, color, spacing, placement, and other characteristics meet the requirements in your area. Always verify current local or state marine regulations before installation.

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

The package contains 144 pieces across 24 sheets. The exact quantity of each individual letter or number is not specified.

Important Information

  • Measure the available area and confirm the required character size before ordering.
  • Application results depend on surface condition and preparation.
  • Do not apply to dusty, oily, wet, rough, porous, or heavily textured surfaces unless the surface manufacturer confirms compatibility.
  • Check applicable local requirements before using the decals for official registration or identification markings.
