I'm not in the same league as you guys. Mine are stock rims - the original ones that came with the truck. They were in poor condition when I bought it. Pulled the tires and took them to the local gravestone dealer for blasting (apparently they cut the letters into the headstones with some kind of special grit). When business is slow - days when not many people go to meet their maker - the two blasting guys just hang around. So they're happy to do side jobs. Better to get even a little money than nothing - I think they asked $5 per rim. That was for both the inboard and outboard faces - and in the wells as needed. The "well" of a rim is that surface under the tire that runs from flange to flange. I had to look that up.
They were taken down to white metal. Brought them home and lightly coated all surfaces with Rustoleum Rust Reformer. Just to prevent any rust bloom - in case I didn't get right to them. The finish coating is another Rustoleum product called Appliance Epoxy Enamel. The stuff is awesome. It goes on and lays down beautifully. It takes one's full attention to get a good finished product however. In light of that, one rim was done at a time. Two coats - one light and one medium - filled any profile created by the blasting grit. When the epoxy is fully dry, it is as smooth and hard as a porcelain sink. Air dried for two days. And then, each night for four nights (after my wife went to bed), they went into the oven. Baked them low (200F) for 2 hours to prevent any remaining VOC's from bubbling out. When it was safe to bring the temp up, I took a chance and went to 300F. They stayed in the oven until morning - before my wife woke up and found a giant rim in the oven. I don't tell her anything. I figure it's easier to apologize than to ask permission.
I got them all baked out in 4 nights. Reinstalled the OEM brass valve stems and then had the rubber remounted and balanced. That was over three years ago and I took this picture the other night - they still look like right out of the factory

BTW - those are the only Rustoleum products I use. The rest of their stuff blows.
