X2 on 25% up front. Just got mine inspected so i asked when he slid the tester over the window. Anything lower and you'll eventually be getting it redone since it won't legally pass. And some cops do carry these testers. I have seen people ticketed and made to rip their tint off right then and there. Never had prob myself. Also if you are doing the top of the windsheild don't go below that as1 line since that can fail you as well.
