Z31 removing the Rubber Side molding for a cleaner look

As many owners of early Z31's have noted, the body thick side molding tends to date the body. As part of my ZX's updated look, removal of the side molding was in order; fortunately, for the '84 and '85 cars, the molding is held in place using 3M adhesive tape only. The downside to removing the molding is that the paint will likely have faded so that you end up with a different color underneath. If you are painting your car, not a problem.

Tools Needed

  • Phillips screwdriver
  • Gasket scraper or putty knife
  • Razor blade scraper
  • Heat gun
  • Goo Gone

The Process

  1. Begin by removing the marker lamps. These are held in place with stainless-steel Phillips head screws on the 84-86 models.

  2. Using a gasket scraper or putty knife, carefully pry the molding away from the body. Tip: Wrap masking tape around the putty knife to prevent scratching the paint.

  3. Carefully lever the molding away from the vehicle. For easier removal, park the car in the sun first to soften the molding.

  4. Remove the original adhesive. Pro Tip: If you're not painting the car, avoid metal scrapers and use a heat gun and plastic putty knife to protect the finish.

  5. Once most of the original adhesive is removed, use mineral spirits and a heat gun to get the last residue off. Caution: Mineral spirits are flammable—work in a ventilated area and keep the heat gun moving to avoid burns or fire.

On '86 models, you will need to fill in the trim holes left behind on the rear quarter panels:

Note the difference in color. On this example, it was due to a respray, but heavy sun fade can also cause a dramatic difference.
