Hello all,
Some quick background. I have been restoring classics and doing body work as a hobbyist for 40+ years. I have completed the bodywork and painted about 15-20 cars over this period. So, I am no professional but still take pride in my work and have progressed through the years to turn out some pretty decent work.
Now to the question. My current project is a 1936 Chevy coupe, when I start a project I always take the car down to bare metal, primer etch, dolly work, filler work(usually with Rage Gold), followed by feather fill and finally hit with 2K primer as a final before moving on to base coat. On my current project I am finishing up the last of the feather fill before I would go on to 2K primer. This time I am thinking about hitting it with a high build primer and guide coat before finishing up with 2K primer. The reason for going with high build primer is to help eliminate those "dimple" spots, usually less than dime size, that I have gotten in this particular build when finishing up the feather fill. By spots I am referring to small high dimple size spots that are barely perceivable. These spots are mainly occurring on the front fenders where there are extreme curves, where the fender shape is literally that of a basketball. I would normally sand the area out to bare metal and shrink it with my stud welder using a shrinking tip followed by filler again. What I'm wondering is if the high build primer can accommodate these dimples? I have never used high build primer, have always worked the metal with dolly, filler and guide coat to pretty much a smooth clean surface, but this extreme curvature is really getting tough to manage.
Thank you to anybody that will enlighten me on these high build primers, I can continue on as I have always done in the past but thought this worth a shot. I'm not looking for short cuts, just something to help me along.
