CLR and scotch brite pad can be used to "tune up the rust patina".
As far as paint ...........a combo of primer red, gray and black with a variety of greens can be faded, blended and sanded back to match the old and new patina.

This is 95% original patina with CLR scotch brite rust treatment and some paint blending on repaired panels then a matte clear over the top.
