To prep the hubcaps, I washed them thoroughly and then scuffed them to a dull finish with a scotch brite sponge.
Then I used a one step rustoleum paint designed for a one coat application.
The color is Colonial Red Satin Finish, a very close match to the russo interior.
I had a Subaru Brat many years back and painted my actual rims red. The Brat was silver with red graphics and I liked the look of the red rims (plus I was low on fundage so new wheels were out of the question). I used Rustoleum as well but no idea of the color - would be funny if it was the same.
I will keep the set like this as-is until I upgrade the wheels/tires. I have a set of 16x7 rota circuit 8's that I plan on installing (with hub rings and wobble bolts)
I will be painting the centers of the wheels the same red color and adding a scorpion or fiat center emblem...
