Other enemies are dirt, brake dust, and other contaminants. All these external components can greatly affect the gloss and shine of your aluminum rim.
Therefore, if you have invested in a brand new or gently used set of aluminum rims, you need to ensure that they are far away from the contact of moisture.
Below, follow some steps to help you paint your rims.
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.
Now, your aluminum wheel is ready for the next step.

Step 1: Cleaning The Rims
First, park your car in a secure place. Using a garden hose, spray your rims with a robust and steady stream of water. Then add a small amount of liquid dish soap or other rim cleaning fluid in a bucket of water and mix thoroughly.
Apply this mixture on each edge and let it soak for about five minutes and then spray with a pressurized jet of water.

Mask the wheel to protect it from overspray. Now, tape the tire. Insert playing cards between the wheel and the tire. Stick the nuts tightly. Cover your brake discs with some masking paper.
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.
Step 6: Apply Clear Coat
The clear coat should be applied in several and thin paints.
