Need to make my new ride with a cheap paint job look like patina!

[HSRACER]

I bought a 72 suburban for the wife today and it came with a pretty decent paint job that was put on over the original dings and scuffs. It isn't good enough to buff out due to the pitting on some of the surfaces before paint was applied.

The wife wants it to look dull and maybe some weathered look. Can anyone give me some ideas or techniques to use that will make this burb look weathered and sun faded?

I think the paint is single stage with no clear on it and seems to be semi think. I have no idea what is underneath. The po stated it was sanded with 400 grit over the stock red/orangish paint then sprayed with the medium blue paint it currently has.

Any help or guidance as always is appreciated.
