Installation Notes

1. Choose a smooth, clean, dry area above the waterline where the decals can be viewed clearly.
2. Check your local registration requirements and arrange the characters for correct order, spacing, and alignment before removing the backing.
3. Clean the surface with rubbing alcohol or a mild soap-and-water solution to remove wax, oil, polish, and debris. Rinse if needed and allow the surface to dry completely.
4. For best adhesion, apply when the surface temperature is approximately 50°F to 90°F (10°C to 32°C).
5. Carefully peel the backing from one decal without touching the adhesive surface.
6. Position the character, then press it onto the surface from the center outward.
7. Use a squeegee, application scraper, or smooth plastic card to press out air bubbles and secure the edges.
8. Repeat for the remaining characters, maintaining a straight line and consistent spacing.
9. Allow the adhesive to set for at least 24 to 48 hours before exposing the vessel to water, washing, or heavy spray.
