I posted a pic of my truck earlier (page 2 of this thread, mid April), and wrote about the plans for it. Now it's looking a bit different, before pic inset here.
I guess this is somewhere between a real patina and a fauxtina job. I just sanded off the gray paintjob as well as I could, washed the rubber seals with thinners, gave the rusty hood a light once over with a DA sander and topped it all off with a light coat of flat clear. The clear is still semi wet in this pic, it's getting matter still when completely dry.
High gloss black wheels with new rubber and chrome acorn nuts make the truck look maintained.
