How To Prep Aluminium Wheels For Paint
To prep your wheel for painting, you have to remove all the contaminants and oil. You can apply aluminum-safe cleaner or a good solvent that can remove all the residues.
After residue removal, blast the wheel with #60 or fine media. Again, remove all the residue with an alloy safe industrial cleaner or good solvent.
At this point, you should be well clothed to avoid contact with contaminants.
The next step is to treat with a phosphoric acid solution. Blow off to remove excess and don't let it dry. Watch for fumes; ensure your mask is well fitted.
Then treat with chromic acid or any other alternative chemical. Prime with urethane or non-etching epoxy. I recommend epoxy.

Step 4: Apply Primer
Spray several layers of light on the primer. Wait for the primer to dry and smooth it with 600-grit sandpaper. Wipe to dry. This will take around 20 minutes.
Step 5: Now Paint
Spray several thin layers of silver wheel paint. It will be a good approach to turn the wheels a few times by driving the car back and forth a few feet to see if you have missed any spots. Let the silver wheel paint dry for 5 minutes.

The clear coat should be applied in several and thin paints.
