Yes, clay bar to clean up whatever is a problem now. You can then get small tube of color-matched paint from the dealer to cover up the dings.
Then, consider getting one of those strong cover material (for example, from

BTW, cloth bras tend to cause more problems than they cure - they need frequent cleaning and washing and drying and breathing time. Sometimes the flapping of the material edges can damage the paint under that spot.
