3M Prestige films are actually meant for buildings while Crystalline Series (CR) is meant for Automotive applications. 3M is launching CR 90 for wind screen applications in Pakistan to have better visibility and also to avoid heat coming through the front screen at the same time avoiding UV and IR to a great extent.
CR 70 is available while CR 90 will be shortly available with 3M dealers in Pakistan.
I have got CR 70 on my Corolla on the side and rear window, desparately awaiting CR 90 to be applied on my car windshield.
I have taken my vehicle upto Kashmir recently and no body objected me due to these negligible tints till Karachi.
