The previous owner drove my M3W with a loose strap over the bonnet. This collected grit and sanded the paint underneath, with a small spot seemingly through the color coat.

It even scratched the chrome on the faux radiator cowling.

As delivered to me from the dealer, the strap had shrunk and couldn't be properly tightened. I soaked the straps, worked conditioner into them and was successful in tightening the strap. The tightened strap naturally covers most of the scratches. But some are exposed. I have done some light polishing, but have been conservative as that just removes more paint.

If I were to try to get some matching paint from a professional automotive paint shop, what do I need to know to select a compatible paint?

Any suggestions about the scratches in the chrome? I do have some chrome polish, but it is very fine and probably more intended to manage discoloration.

The car is meant to be driven, so it doesn't need to perfect, but I do want to take care of it.

Thanks.
