Maybe I'm looking for a magic bullet, but does anyone know of a good, durable, one step chassis paint (black)? I have the roadster pickup frame boxed, bracketed, and wire brushed. Some of it is 74 year old steel, pitted and rusty but wire brushed to remove any loose scaly rust, some of it is new steel, and much of it is welded. This frame will not show, as I am running a full fender package, but I would like to paint it a nice gloss or semi gloss black paint, that does not need a primer. I want to spray or brush this frame once, and be done with it. In the past I have always used a good primer, then sanded the primer, then topcoated with acrylic enamel, but this was on highboy roadsters where the frame was exposed and had to be flawless. Now I am older and lazier, and this frame ain't gonna show anyways, so can anyone suggest a good , one step, chassis paint.
