Troubleshooting & FAQ
What surfaces are these stickers suitable for?
These vinyl stickers are recommended for smooth, clean surfaces like paper, glass, and painted metal. They are commonly used for boat registration, mailboxes, house addresses, classroom displays, and window signs.
Are the decals truly waterproof for marine use?
Yes, the vinyl material is waterproof and UV-resistant, making it suitable for boats and other outdoor applications. However, for best results in wet conditions, ensure the surface is completely clean, dry, and non-porous before application and allow the adhesive to set properly.
How many of each letter and number are included?
The package contains 24 sheets with a total of 144 individual 3-inch characters. The exact count for each specific letter or number is not specified by the manufacturer.
My stickers are peeling. What can I do?
Peeling is typically caused by surface contamination. Ensure the application area is cleaned with an appropriate solvent to remove all traces of dirt, oil, wax, or polish. Applying a new decal to a properly prepared surface is the best solution.
Can these be used for official boat registration numbers?
Yes, the 3-inch character size meets the requirements for boat registration numbers in many jurisdictions. Always confirm local regulations for specific sizing, color, and placement rules.
