  2. Grasping the wheel flare with 2 hands by the attachment flange and beginning at the lower end begin to pull it free of the body.
  3. In most cases especially if the flare was recently applied the flare will pull free leaving the minimum of tape residue. If acrylic foam residue is left on the painted body use a 3M Scotchbrite molding adhesive and strip removal disc (3M part 07501) or the equivalent. Follow the instructions and be sure not to exceed 4500 RPM spindle speed. The rotating disc will remove all the tape residue from the body without damaging the paintwork.

Installation Procedure

Important: Apply in an environment that is free from dust or other dirt that could come in contact with the sticky backing. This could cause improper adhesion.

  1. Clean the area where the molding or the emblem will be mounted.
  2. Use a suitable solvent, such as a mixture of 50 percent alcohol and 50 percent water in order to clean the areas.

  3. Dry the areas thoroughly.
  4. The area should be at room temperature. (20.9-23.6°C or 70-75°F) for proper adhesion.
