Frequently Asked Questions

What is the best technique for applying this emblem?

Always work from the center of the emblem outward during the application process. This technique effectively pushes air and any application fluid toward the edges, preventing the formation of trapped bubbles. Using a felt-edge squeegee is highly recommended to provide even pressure without scratching the delicate vinyl surface.

Should I use heat when applying the decal to curved surfaces?

On complex compound curves, applying gentle heat with a heat gun can help the vinyl conform to the panel without wrinkling. Keep the heat source moving and maintain a safe distance. Always apply heat after the initial placement to set the adhesive and ensure the graphic follows the contours of the tail section.

For the best results, use a felt-edge squeegee to apply pressure from the center outward, ensuring all air is removed from under the vinyl.
