3M Protective Film Installation:
Dee Zee mudflaps are designed to fit snugly into the wheel well. To protect your vehicle,
Dee Zee has included a 3M protective film.
1) Hold the mudflap up to wheel well to determine 3M protective film placement.
2) Thoroughly clean the area where the film is to be installed using 3M brand adhesive cleaner
or other petroleum distillate based cleaner.
3) Cut the film to the proper shape for your application.
4) Mix a solution of water and dishwasher detergent into a spray bottle.
5) Remove film from the protective liner and spray with the water solution.
6) Apply the film to the fender, adhesive side down and spray total area with water solution.
7) Remove any air bubbles in film using a wet sponge.
8) Let film dry completely before installing mud flap.
