Introduction: Paint Your Rims Cheap!
In this Instructable I will show you how to give your ride a facelift by painting your rusty or chipping rims. I've done this on 3 of my cars now and I've learned that it takes a good deal of patience and prep-work. I was sick of my Subaru looking like a grocery getter, so I picked a nice gloss black to replace the flaking silver.
In this Instructable you will need:
-various grits of sandpaper
-Self Etching Primer
-"Stops Rust" paint
Step 1: Prep the Wheels
In order to get the paint to stick and be durable, it is imperative that you remove any flaking, rusting, or chipping. To get rid of the bulk of it I used a wire brush attached to a drill. This saved me a lot of time and elbow grease. I know not all of you have this, so a good sanding and a wire brush will do the same, just not as easily.
Once you're done getting rid of the flakiness you reach for the sandpaper. You should use 150 grit sandpaper to really rough-up the surface. Your goal here should be removing anything shiny or rusty. If you used the drill, make sure you smooth out any deep grooves you cut in it. I didn't do this so well so now I have some nasty cuts in my finished wheel.
After the sandpaper, get out some steel wool. I used the finest stuff, I think it's 0000. But 000 should woork too. Make sure you hit every spot on the rim, getting a nice even dullness.
Finally get rid of all the dust and debris with a rag. Then hit each wheel with a rag of mineral spirits or paint thinner. Again, make sure you get all of the wheel. Wipe it up with clean paper towels and let it dry for 5 minutes.
Now you're ready to tape!
Step 2: Tape Off the Tire
To prevent over-spray on your tires you need to tape where the rim meets the tire. I tore strips of painters tape into 3-4 inch pieces. Then I stuck them in the groove overlapping about 1/2 an inch. After I went around the whole wheel I tore strips of some paper that I found in the recycle. Newspaper is the perfect paper to use. Make sure you cover the tops of the tires, paint will settle everywhere.
Finally, tape the valve stem. This should only be one piece of tape if you do it right. If you are using black paint it's not too big of a deal, you just don't want it gummed up with the paint.
Step 3: Apply the Primer
After perusing the internet I found out that Self Etching Primer is the best. The primer helps the paint stick to the wheel for a lasting result. To apply the primer, hold the can 8-10 inches away from the wheel, don't just hold down on the trigger. You want to pulsate your finger every second or so, moving at all times. Make sure you don't hold it down too long in the same spot otherwise it will drip and look terrible.
After the first coat, wait 20 minutes and apply a second coat of primer. You can do a third coat if you would like, but I stuck with two. After your final coat of primer let the wheels sit for 2 hours. From what I read this lets the primer fully cure and dry and will help for a lasting result.
Step 4: Paint!
Now you finally get to apply your final coats. Again, patience is a virtue. Make sure you don't coat it too thickly, otherwise it will drip. Your first 2 coats should be relatively thin, waiting 20 minutes between coats. And on your final coat make sure it's pretty thick so it brings out the true finish of the paint. Make sure you get a good amount of paint everywhere for your final coat.
Once your last coat is done, let it sit overnight, or a few hours at least if it's warm. To top it all off, give your lug nuts a good scrubbing with a wire brush. I used a Vise-Grips to hold the lug nuts in place while I got the rust off.
Step 5: Mount Them and Admire
Alas, remove the tape and mount your wheels. Stand back and take a good look at your handiwork. You will now be the talk of your town, and if done right, the rims will last for years. Congrats!
