I used Paul's Chrome over 12 years ago. I think they are in Pa. Keystone I think does an exchange thing. Just note that there are many level/quality of finishes available. I had "Show Chrome" for my '72 Skylark. Cost 3 times that for each, but came out Really nice ! Paul's Chrome also warranties the work. Shop around, decide what you are looking to have done. Just realize a lot of labor in the prep work is the bulk of the cost and depends on how many layers you get. Most are three step process. Good Luck
