Now it's time to work on the door to body fitment. Instead of using Bondo my preference is to build up low areas using fiberglass. I removed the primer from all the areas that were either mismatched or too low. Duct tape was placed to channel excess fiberglass resin away from the rest of the car.
The fiberglass was cut at all the door gaps using our Fein Multimaster tool. Door gaps were then sanded open to the proper width using a small piece of sheet metal wrapped with sandpaper.
The 2 inch square fiberglass patch in this picture was done over a year ago when we reinstalled the B-pillar. I ground this area paper thin then used it as a form for the fiberglass we applied today. Remember, the fiberglass we use is clear which means the patch you see is on the backside.
