1-1/8" Bold Line Body Side Molding

1. 1

   First, keep in mind that the ideal temperature for this work is 65 degrees Fahrenheit. Mark the exact area you want to install the body side molding by outlining it with a tape that can safely adhere to your car’s paint without damaging it during removal. Painters tape should work, but you may want to test it first on an inconspicuous area, just to be sure. Once satisfied with your choice of tape, and with the precise location of your body side molding, run a long strip of tape just above the length of the area. When the time comes for installation, you can just follow the line by applying your molding directly under the lower edge of the tape.

   Prepare this area by removing any and all dust, grease, soot, or grime from where you want the body side molding to stick. Cleaning it well with soap and water, then drying it effectively with a lint-free cloth is the minimum requirement for this step. You should also use a car-paint-safe solvent to remove any trace of oils or other greasy residue to provide an ideal surface for the body side molding adhesive. Use a 50/50 mixture of rubbing alcohol and water on a soft cloth to clean the surface.

3. 3

   Cut the molding to the proper lengths to fit where it’s needed. We recommend using shears for a clean, quick cut. Peel the backing off of the first stretch of body side molding to be applied, then begin sticking it to the vehicle at the pre-set line. Move slowly but evenly, smoothing out the molding with steady pressure as you go to ensure that it stays level and straight. Avoid touching the adhesive side or allowing any dirt or debris to come into contact with it during the installation. Once the entire strip has been applied, run a soft cloth along it from start to finish.

4. 4

   Remove the guiding tape, and allow the body side molding adhesive to sit for several days before washing the car or otherwise allowing the strips to be disturbed. Once the molding is firmly in place, the only thing left to do is drive!
