I want to paint my rims due to scuff in them. I started to sand them down alittle bit so that the scuffs are out, now my question is when I apply the primer should I sand it then? and after I sand the primer should I spray a fresh coat of primer before spraying the paint onto it?

are they chrome because there is alot of mixed feelings about painting chrome.....some say its possible others say its not

o btw google is your friend :)

Most primers have a tendancy to leave a "grainy" or "rough" texture, so it is a good idea to sand it with a 600 grit (or finer) sandpaper. A second coat is not necessary or recommended!
If the wheels are chrome or aluminum, they can be painted, but a slightly different procedure is required. If so, let me know!
