I ordered directly from the UK:
Alloy Wheel Repairs, Protection, Refurbishment, Cleaning & Polishing
A set of 5 costs 69.90 GBP or $112.04 to buy purchase and ship to the US.
Sameday is a scratch/dent/alloy wheel repair franchise on the west coast but since it is supposedly DIY, any place that does rim work should be able to do install it. The guy at Sameday never saw one before, but he went on-line, looked at videos and did a great job with the install.
