I'm planning to put 35% all over, not the windshield, of course. A local shop quoted me $185 to do all 5 windows and it comes with a lifetime warranty so I'll consider that. Here's a pic of our van with 35% up front and factory tint in the back:



The guy tinted the front windows for $55 and it comes with a lifetime warranty so it's a pretty good deal. I think I will go back to him to tint my car's windows too.
