Find a paintless dent removal place in your town...as your dealership who they use for paintless dent removal...if they are good enough for the dealership they will perform great work on your vehicle as well
If its not a terribly bad ding, your best bet is probably a good paintless dent repair person. We've got a couple guys around here that can work magic. If the paint is cracked or it's more substantial than that, a good collision shop is your next best bet. Make sure they're good with paint matching, and not dependent on paint codes, *especially* if it's metallic.
