I've always loved those paint jobs from that era too.
I remember a neighbor that used to do these types of paint jobs in his garage. He was real good. I remember seeing cars with lace paint and paint jobs that resembled fish scales and alligator hide, as well as murals with space scenes, stars and planets, ect. He did cars, vans and motorcycles. There weren't very many pick-ups being done in those days. That was a long time ago. I think I was in Junior High at the time.
I also remember seeing cars like that in magazines like Hot Rod and PHR back then too. Of course, I was dreaming up the car that I wanted when I turned sixteen, so naturally, some of these paint schemes figured into it. That never came to be, but I've often thought about trying to use a few of these paint ideas today to kind of build the car that I would've built back then.
