Clean your rims good, If not no worries you'll sand it off ne ways.
then i Sanded them down removed the clear coat, Cleaned them up with a microfber cloth to remove all that crap i just removed.
Then Taped all the rims up and then Painted them nice even coats. The first few coats are just a prime. Then as you get into the 5th coat they start to look nice. Make sure you get that clearcoat off the rims tho, If not youll know it and the paint wont stick to that area.
Took me about 6 hours. Dont rush... You take your time there gona look nice. You rush and well... You know.
Oh and the tape around the tires, Yeah that was hard to get it to stick to the rubber. I dont know if it was because of the old tire shine on them or cus they were dirty, But i had to up it to duct tape.
Have fun and post pics when your done.
