i have VIP (3% vis) 97% all around (front/rear sides/rear) and 50% on my front windshield here in FL.. summer days my car is nice and cool..
just put ur fronts down when they put on lights.. and lock em.. and if he asks be like they dont come up.. he cant by law MAKE u put them up. and in most states they dont care about rears and the laws are more lax..
i know here front sides is like 50% max... and backs can be... 70?
but like i said i drive 97% and... 50% on the actual windshield w/ not one ticket
