I found out (according to Toyota) they do NOT do gold badges for the Camry '07 and moving forward. Two delaers told me this. Maybe another "trustworthy" dealer offers the service or has info on it.

I agree about using something that tarnishes, peels, etc in that it looks bad after a bit. Depending on the cost (and how long it lasts) maybe get 2 sets - one for back up?
