I just had my windows tinted in Austin by Mother's Window tint and they look great. Cost me $149. While I was there I heard the manager take a call from a guy that wanted darker than legal on his car. I think Texas law is 35% and he wanted 5% (I think that's light coming thru but I'm not sure). The manager politely told him what was legal in Texas and offered to do it for him at a reasonable rate and a professional job. The guy hung up on him. It was nice to hear the manager being honest, legal, and polite. Plus, my smart looks really cool (and cooler on the inside).
