hey guys got a question hopefully you have an answer to this. I have a customer that has a car that has a lot of exterior chromed plastis parts. But this car has been neglected a little so it has created lots of water marks on this particular pieces and make me look like the job is not done. I have tried everything i can think of. I dont want to use anything that is meant for chrome metal in case of discoloration since like i said this is plastic. Any ideas on how to get rid of these pesky spots. :wha
