I just got my new 2019 GT Stinger a few days ago (LOVING IT) in Panthera Metal. I noticed later the chrome accents have this spottiness and discoloration. I assume this isn't normal. I wasn't sure if anyone knew whether this just needed to be cleaned using a certain product or if these need to be replaced by the dealer. I took it through a car wash yesterday which did not get rid of this. Any suggestions or help would be greatly appreciated.
