Removal Procedure


    Object Number: 521815  Size: SH
  1. Using a small tip flat screwdriver in the cut-outs provided, begin to pry out the central black pin in the wheel flare retainers. When the pin is extracted about 0.75 mm (0.03 in) or so the pin can be pulled free of the retainer with the thumb and the forefinger. The retainer body can then be extracted from the flare and body hole location. It may be necessary to shake the flare body. Continue around the wheel opening until all the retainers are removed.
  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.

  2. Use a suitable solvent, such as a mixture of 50 percent alcohol and 50 percent water in order to clean the areas.

  6. Install a new wheel flare, locating first the molded in locator followed by engaging the individual push-pins.
  7. Remove the red tape liner by pulling on the 2 tape tabs provided. Pull steadily and as close as possible to the direction of the tape strip to avoid tearing the red tape liner before the tape liner is fully removed. If the tape liner should tear before the tape liner is fully removed grasp the second tape tab provided and pull from the other direction.
  8. Finally, wet-out the adhesive tape by using a hand-held hard rubber roller. A pressure of about 15 lb is required which can easily be developed by using bodyweight to lean against the roller.
