I was going to ask the same question.
Because the caliper itself looks like a harsh cleaner was also used -on both cases shown in this thread- then I understand now why StopTech is saying that their exchange will be a one-time deal.
That or the Trophy finish is really very delicate. My old and current OEM calipers were painted with VHT caliper paint and they never looked like that after using the OEM wheel cleaner. They are still quite shiny...
