very simple...

Blue Tape/Green Tape: Short term, usually delivery
3M clear bra: ongoing protection

I wouldn't want to have a clear bra installed by some shop I have never delat with in a city 1000 miles away. You can't easily take it backto get it fixed if there are bubbles, or if something doesn't turn out right. Get it done locally by a trusted shop, like ryan at http://www.autopaintguard.com/
