I did some grinding in and near my car. I had the sunroof out, so I put a tarp over it. Super-fine metal sawdust got on the car, and rusted on the surface (especially under the tarp). It's in the paint, not the metal. Suggestions? If it's notsomething I can fix, what's a good paint shop?
I don't want it to get any worse, so I need to act now.
