Troubleshooting & FAQ
Are these letters compliant with Coast Guard regulations?
The 3-inch character height is intended for applications where 3-inch registration characters are required. Compliance also depends on character spacing, contrast, placement, state or local rules, and the vessel type. Verify the requirements for your jurisdiction before installation.
Will these stick to an inflatable boat or a textured surface?
These decals are designed for smooth, hard, non-porous surfaces such as fiberglass, gel-coat, aluminum, and glass. Adhesion on flexible PVC, fabric, rubber, heavily textured, dirty, waxed, or porous surfaces may be unreliable.
How many of each letter and number are included?
The kit contains four full sets of the alphabet, A-Z, and numbers, 0-9.
Are the letters individual or on a single sheet?
The letters and numbers are individual peel-and-stick decals arranged on backing sheets for handling and application.
Can these be removed and reused?
No. The permanent adhesive is intended for single use. Removing a decal may damage it and can reduce its ability to adhere again.
What is the best way to ensure the letters are straight?
Use a measuring tape and a pencil or non-permanent marker to create a level guideline before placing the decals. Apply the characters one at a time and check their alignment as you proceed.
Is this an OEM product?
This listing describes an aftermarket vinyl decal kit. The reference numbers above are included only as comparison references and do not independently establish OEM status or guaranteed interchangeability.
