Someone hit my rear bumper enough to scrap the paint off but not damage or crack the bumper. I think I can just sand the paint down a little and if I get the same color paint fix the appearance. Does anyone know how to get some paint that is close to the bumper color? Can I just take a flaked chip to a paint store and get them to match it up? Seems like the dealership will try to rip me off for something like this. Any suggestions?
