I'm by no means an expert, but I thought I would share how I painted my wheels in case anyone else wanted to do the same. It is a good way to save some money and completely change the look of your truck. I'll post the way I did mine, although some of the steps are optional.
First you'll need your material:
-Duplicolor wheel paint
-Duplicolor clear coat
-Spray can gun
-400 grit sandpaper
The first thing I did was wipe down the wheels with some simple green to clean them up.
Then I used some brillo pads to scuff them up a bit and to completely remove all traces of dirt and grime. I kept my wheels really clean so this wasn't too bad, although it may be harder if your wheels are coated in crap.
After brillo pads:
Then take a sanding block and sandpaper and go to town. This was the most tedious step, as you want to make sure to scuff everything up so you have a good bonding surface for the paint. I ripped up some small pieces of sandpaper to get in the smaller grooves. Then use some more degreaser and make sure everything is cleaned up nicely.
Now mask off your wheels. I used some index cards between the wheel and tire and then masked off the surrounding tire with newspaper. I also stuffed some newspaper between the spokes to avoid painting the rotors. Now use some self-etching primer. I put on two light coats with about ten minutes between coats. Working around the truck with all four tires gives enough time so you shouldn't have to wait any--just keep moving. I was diggin' the army green color, although my neighbors were looking at me like I was crazy.
After letting the primer dry for 30 minutes or so it's time to paint. Grab some of the wheel paint and do light
coats. This is always my problem as I like to lay on coats heavier to make sure it's covered evenly. Trust me, light coats and you'll be fine. The first and even second coats may not cover all parts of the wheel, but after a few more light coats it will look great. Same as with the primer, if you're working around all four wheels you shouldn't have to wait between coats.
After first coat (I still think I went too heavy here):
After five coats:
I let the paint dry for 45 minutes and started the clear coat. I did four light coats using the same light coat principle. You can vary this based on how glossy you want your wheels to be. Looking back I wish I'd have done less clear and gone with a more matte finish since my tires are so faded.
