Sounds good to me....I'll "get on that" this weekend and tell you what happens (about the defroster of course).
Now that you mention it I do remember me and my buddies getting in the car after playing some basketball last winter. It fogged up on the inside real quick, and the defroster worked good and cleared it up in no time.......beacuse it was on the inside. I see what you mean about it being designed for the inside only.
I see what you're saying now....and maybe I don't have a problem.
I'm defenetly going to do the experiment though!!
