removing tint
 

is there a proper procedure to do this or should I just go at it with a razor and some windex. What about the area on the back windshield with the dot matrix, is there a right way to do that part?

Use ammonia, not windex.

What he said. But I'd dilute the ammonia with water because if you don't, that shit will knock you the hell out!

You can also use simple green. Spray it on the inside of the windows, then put a black trash bag on over, cut it to size and leave it on for an hour in the sun. Then after that, just use the razor blade to pry up a piece big enough to grab. Then just pull it off. Make sure it both pieces come off at the same time. I used this as a reference and did this a few days ago. http://www.tintdude.com/remove.html
