You would have to sand down the rims and smooth out or remove all the clear coat with 650 grit wet sand paper, but you don't have to use it wet. Just as long as the sand paper is for metal, that's fine. You will have to sand more than once and get the grit up to 1000 grit.
And then tape off the area and reapply a high adhesion clear coat. But if it has chpped from the factory, it might do it again.
Make sure you clean then with thinners and then alcohol before you paint.
