Body work and paint

Here is my take on it. Metal work is, at least to me, rust repair, dent repair and panel replacement. Once it goes to the body shop, everything else is done. Different shops may have different steps, but likely steps (at least the way I do it) would include:
Prep bare metal and shoot Epoxy primer to protect the metal from rusting, do filler work and sand it to perfection, shoot high build primer, block sand, fix any minor flaws found, more primer, more block sanding, wet sand, paint, clear coat, cut and buff, assemble the car. Every step is time consuming.
