This is an Instructables on how to remove stubborn brake dust from a magnesium or aluminum car wheel. Also on how to paint one.
Here is the list of items needed to get started.
klean-strip ks-3 premium paint stripper
Rustoleum universal all surface paint spray can (I picked flat black)
cheap paint brush
plastic scrubbing pad
outdoor faucets and hose with spray head
masking paper or newspaper
protective eye wear
small metal bowl
Step 1: Step One
First, loosen the nuts just a little to the point where it easy to spin it off. then jack the car up. Make sure it on a jack stand, DO NOT LEAVE IT ON THE JACK! Continue to remove the nuts. It may be difficult to remove the wheel. Take a 3 lbs hand sledge hammer and hit it behind the wheel. It should pop right off. Roll it to a place where there is plenty of ventilation. I did this outside on a sunny day.
Step 2: Step 2
After removing the tire, lay it flat on the ground.
I use Klean-strip ks-3 premium stripper. This is very caustic and corrosive, hence the reason to use protective eye wears and latex gloves.
It will also eat disposable plastic cups so don't use those. Use a small metal bowl.
Apply a good layer of stripper on the wheel. be sure to keep it off the rubber tire.
You can see it working almost instantly. Let it sit for 30 minutes.
spray it off outside with hose.
check for stubborn spots and reapply.
after you done washing it off, use a plastic scrubbing pad and scrub down the wheel for small stubborn spot and to smooth out the surface a little.
Step 3: Step 3
You can use a small polishing wheel that you can buy at home depot for 15 bucks. But Since This used to be a shiny wheel and I didnt want to be wasting my time cleaning it so I decided to paint it.
I use Rustoleum Universal All Surface Paint for this job.
First take a paper towel wet with acetone and lightly clean the surface of the wheel. be sure not to leave behind any lints.
Mask the tire with masking paper or newspaper and use masking tapes. Don't use duct tape. it will leave behind adhesive.
Lightly spray the wheel. wait 5 minutes between coats. This is to avoid runs.
After painting, let it cure overnight before installation or driving the car.
Step 4: Step 4
Put the tire back on the bolt. You can coat the bolt with antiseize at this point. Tighten the bolts and make sure the back of the wheel is flushed with the hub. Lower the car downand torque the bolts to specifications. DO NOT IMPACT GUN IT! It will make removing the nuts next time extremely difficult! (think you gonna have an impact gun with you on the highway when your tire blow out?)

This is my messy garage with many incomplete projects. Sometime my ADHD get the best of me. My girlfriend isn't happy with this.
