Ok so I'm a grown man now but back in 1976 I had some sweet hot wheels. I wish I could remember who the little turd was that I gave them too. So I did have a few that I kept and =one is a 36 ford coupe, solid purple, white inter with black backrest seat.....well I guess I didn't like purple so I used some Estes model paint, It turned out nice...silver mixed with blue...but it kind of sucks now. Im not sure it will come off but it seems to flake off pretty nice...so Im guessing a pressure washer is out of the question? any ideas??
