I used rustolem products because of the availability. Since the bumpers had so many chips and rust. I sanded them with a DA and my mouse. I used a spray rust converter on all the bare metal rust spots. Let dry 24 hours then used the self etching primer, then several coats of filler primer, sanded between coats then used the primer sealer before top coating with a Rustoleum saitin black. I used the Fusion paint for the end caps but did not get all the armorall off so got some fish eyes. All the primers might be overkill but thought I would try it and see how it holds up to our Wisconsin winters. Hope this helps. If more questions feel free to ask. Rustoleum car primers are now available at Menards and Wal-Mart. Our host might have some better products?
The rims are next. I have some graphite metalic I am going to use for the centers and the lips will be silver, like the factory paint but darker centers.
