The thing is, as inconsistent and hyper a nation that we are, our Police either let you go without even staring and sometimes they will harass you for no obvious reason just because he was ripped off last night for having bought something called local Viagra that didn't live up to his or somebody else's expectations. He stands justified in tearing off the just installed tints (whether you sold your kidney to buy 3M or the Spectrum, the so called "3M equivalent" for less). Police is totally inconsistent and unpredictable. So if you are willing to gamble Rs.2500 or 15000, its your call.
Second. The Jaali or screens may not look cool, but tell me, what do you really want? Keep cool or look cool? Like other members suggested, my advise would be to invest in insulation of your ride. That will give you more bang for your buck despite the fact that in scorching heat, nothing works (in our scenario, please stop looking at the couple n the E Class, that just whizzed by) except that tall glass of Lassi under the shady tree.
