primer job
n.— «Once disgraced, now embraced, rat rods are becoming one of the hottest trends among backyard mechanics since the tail fin. Also called the primer job, lowbuck, or rat-a-billy, rat rods are used cars with attitude. They are often Frankensteinian amalgams of old cars put together—the cheaper and dowdier, the better.» —“Backstory: No paint, no problem” by Patrik Jonsson in Greer, S.C.
