METAL WORK AND BODY FILLER
CoupeKing had handled the majority of the cutting and welding, but to make sure that the body work required a minimal amount of body filler, some fine metal working was still necessary. So out came the hammer and dolly. This is a time honored metal working technique that requires both skill and tremendous patience to master. While the principle is simple, hammering sheet metal against an object that has the shape you want in order to achieve show worthy results is anything but. The team at Diamond Hills is filled with true craftsmen, so within a few weeks they had the body panels where they wanted them and began applying the body filler. There are a few tricks to using body filler correctly but the most important one is simple patience. First, the panels must have a sanded finish and be contaminant free. If the surface is not prepped correctly then the bonding agents will not function properly and you will get cracking in no time. Next, the filler should be applied in a thin coat. The less that is used the better. Too often, we see filler applied too thick at one time and in the worst case you can lose the lines of the car.
Once each layer is applied and cured, out comes the sanding blocks and the surface is sanded even. Where the metal begins to show back through the filler is where the high spots are, and where it still remains are the low spots. Repeat these steps as needed until the panels are straight and smooth enough for primer. This is exactly what the Clarion Builds BMW 2002 underwent and after a few weeks of hard work the car moved on to the next stage, primer.
