The stuff is available at most any place that sells a lot of detailing supplies. It's just tape. Peel off your tape, clean up the surface with rubbing alcohol, and apply the new stuff. Should cost you less than $20. I doubt the dealer will cover it, but its worth a shot I guess. Easier for me to just put in on myself, and use the leftovers elsewhere.

Here's a link to an online store that sell it...
