Here is the correct paint. Can on the left is for the back side of the wheels and the jack base, Can on the right is for the front side of the wheel. Despite what it says, do not clear coat if you want a correct finish. That's what I've gathered from reading the posts of people who know this kinda stuff.
That is, if you want to paint them back stock.
