On my truck there is a spot on the door sill where the previous owner must have sanded down... with their pant leg... something fierce. I'd say it's a quarter inch tall, by 18 inches long, of paint removal. It's on the door sill, where the metal goes from horizontal to vertical.
The metal is still very shiny, even after sitting for four months in my yard. The area is very well protected by the door, the area is inside the door seal so I don't think it will ever see water. Except for what is tracked in by me, in winter. I have to wonder if there is a thick layer of zinc/some sort of metal protection layer here.
Rather than mask off the entire door area so as to avoid keeping primer outside of the car, I'm wondering if I can expect reasonable adhesion with the touchup paint? Even if I kill a bottle (at $9 a pop) it's still cheaper than primer and then whatever it'd cost for a matching spray can. I don't care about having to touch it up every so often, since I have to do that anyhow on the hood. The metal is smooth but not perfectly so, not sure exactly what they dragged across this surface.
