i am also in favour of tints...
but only 25% tint shud be allowed for the front 2 windows. and maximum 50% tint shud be allowed for rear windows... 75% and 100% tint shud be illegal..
25% tint takes care of the heat problem... and i dont feel a thing with ac running in my car...with just 4 windows tinted 25%, i havent tinted the rear screen,,
i have never been pulled over by cops in islamabad, rawalpindi, lahore, peshawer or even karachi when i visiited in january.
