In the past, when Team 95 needed more window tape, we got a big honkin' roll of it by talking nicely to the local car dealer (GM, I think). We've moved workshops 4 or 5 times since then, so we probably don't have it anymore, but if I see it, I'll let you know.

Edit: A quick web search shows that JC Whitney (jcwhitney.com) sells what looks to be the right tape. Item ZX157870B for 20 feet of it.
