Making new paint look old??

[PeteVS]

I've been working on an AV8 roadster for many years now and I finally have it running and registered. Still lots to do but I'm hoping to paint it next year. It's a brand new Brookville body ('29), I have a couple of coats of rattle can primer on it and I don't really care whether or not it has a beautiful 12 coats of lacquer and clear gorgeous paint. I have a '63 Chevy coupe with well worn original paint and I'm very happy with it. I'd like the roadster to have the same sort of patina. Are there any suggestions?
