Hi guys...pls advice me on these tints. which to choose. Either 3M or HO. If 3M i ll go for Crystalline 70 (front) & Nano40 (side & rear) while for HO is Ser60 (front) & Ceramic40 (side & rear). At first I wanna go for HO but SA told me its a bit expensive because the IRR is 80-83% compares to IRR99% for 3M. Any suggestion? Pricing is almost similar
