I have been doing a little work on the '55 Chevy while I wait for paint to come in. To be honest, I have never done more than spray an undercarriage black, so I am looking for some detail advice. I know the gas tank should be a silver color. Does the spare wheel well stay in primer? What about where the floor plan turns up at the front of the car? A quick Google search didn't turn up very many factory stock photos of the undercarriage, which is what I am shooting for (or at least as close as my skills will get me). This is what I have so far. I tried masking the frame and had a lot of difficulty with the tape, so I just free handed it with a brush. Any tips or advice will be much appreciated.
