I guess this thread goes to show that the only stupid question is the one that isn't asked. With all the high tech discussions going on I though asking about wiper blades was kind of lame. I learned some stuff though so thanks for all your input.

P.S. Bats, bugs, squirrels, trees ... something's pissing on my Proton. Might just have to camp out one night with a slingshot (bad tree ... bad tree ... take that up your knot hole).
