Bought the Rim tape on ebay about 3 years ago. The seller is no longer around but there are several vendors that carry the stuff. It's very durable. Yes I would prefer the rims had painted stripes but this is very inexpensive and looks pretty good IMHO. You must be patient putting it on. It comes in 4 peices for each side. Below is a link on ebay that looks like the same as mine. It's so cheap I ordered extra. That way you will have backup (that will match).

Good luck.

Cheaper and easier yet.... Go to the local auto parts store or even wall mart and get "pin stripe" from there. It comes on a roll, not sure of how much but I did both wheels, both sides and still had plenty left over. Go slow and don't press it down until you're for sure.
