Installation Notes

  1. Clean the application area with soap and water or rubbing alcohol. Allow the surface to dry completely and remove wax, dirt, grease, and oils.
  2. Measure the application area and use masking tape to create a straight, level guideline.
  3. Plan the character order and spacing before removing the backing. Follow the spacing and placement requirements for your registration jurisdiction.
  4. Peel each character from its paper backing without touching the adhesive surface.
  5. Apply each character from one edge and smooth it firmly with a squeegee or clean card to remove air bubbles.
  6. Repeat for all characters, maintaining consistent spacing and alignment.
  7. Press each decal down firmly and carefully remove the guideline tape.

Troubleshooting & FAQ

Are these decals compliant with US Coast Guard or state regulations?

The characters are 3 inches tall and designed for registration-number applications, but exact requirements vary by jurisdiction. Confirm character height, font, color, spacing, and placement with the applicable boating authority before installation.

How many registration numbers can I create with this kit?

The package includes four complete sets of letters A-Z and numbers 0-9, providing 144 individual characters. This allows repeated use of characters when applying the same registration number to both sides of a vessel, subject to the length of the number and local requirements.

What surfaces can I apply these decals to?

They are intended for clean, smooth marine surfaces such as gel coat, fiberglass, aluminum, metal, painted surfaces, wood, SMC, and plastic. Surface condition, cleanliness, texture, and temperature affect adhesion.

How do these DIY decals compare with custom pre-spaced registration kits?

This is a DIY kit with individual peel-and-stick characters, allowing you to choose the character order and spacing. Custom kits typically arrange the registration number on application tape for a faster, more uniform installation.

What is the best way to keep the numbers aligned?

Use masking tape as a straight-edge guide. Place the tape where you want the bottom edge of the characters to align, then apply each character along the guide while maintaining the required spacing.

Can I remove the decals?

Removal is possible, but the permanent adhesive may require gentle heat to soften the vinyl. An appropriate adhesive remover can help clean residue; test any remover on an inconspicuous area first.

Is this an OEM part?

This listing is for an aftermarket replacement decal kit and is not represented as an OEM product.

What are the shipping speed and cost?

Shipping availability, delivery estimates, and cost are calculated at checkout based on the destination and service selected.

What is the warranty and return policy?

Warranty coverage and return eligibility are subject to the seller's current policies. Contact support with your order details if the product arrives damaged or has a manufacturing issue.

Safety & Important Info

  • Confirm the required registration-number size, color, spacing, and placement before installation.
  • Do not apply decals to dirty, waxed, oily, wet, or excessively rough surfaces.
  • This is an aftermarket replacement decal kit, not an OEM component.
  • Allow the adhesive to bond fully according to the material and installation conditions before exposing the decals to heavy water use.
