1994-2004 quarter window trim is a common area of the SN chassis and normally shows years of sun fade and wear. Overall, this exterior area of your Mustang can stick out like a sore thumb for any SN or New Edge application. Follow along as Uncle Ted and Landan go over the steps on the proper restoration process of these trim pieces.


Prep Process

  1. To begin, make sure to thoroughly clean the surface with a lint-free towel and denatured alcohol.

  5. Now, we can start with the sanding process. Using a course 220 grit sandpaper, sand the entire surface of the trim. Do not concentrate on just the damaged area here, and make sure you use light pressure when sanding. Continue sanding until all pitting is a level as possible.

Primer and Paint Process

  1. Once you have everything prepped and masked off, we can begin the primer process. Clean off the surface one last time to remove all oils and greases. Begin by applying a few very light coats and allow 5-10 mins of drying time.

  3. After your first coat has dried, apply a slightly thicker coat. Again, make sure to allow an additional 5-10 for dry time. Repeat this process for coat 3, 4, and then coat 5 of your primer.

  5. After your primer has completely dried, we can now move in with 400 grit sandpaper and wet sand the area. Make sure to spray this down frequently and apply light pressure here. After you have completed the sanding with 400 grit paper, you can repeat this process using 600 grit. Thoroughly dry the surface and you can then clean it one last time with a lint-free towel and denatured alcohol.
