Hey guys, i have a 2001 320Ci, with 19'' M3 rims. I have scratches around the edges of the rim, like right next to the inner of the tyres. What would be the best way to buff out the scratches?

depends how deep they are

if they are more than a few mm deep, use newtech, or some other metal-based filler
but then you have to paint the rims too
