I use 3m crystalline 70 for all sides (front, back, left, right)
your front windscreen unable comply as well because the screen alone already blocked few percent vlt, then you add up 70%, end up your windscreen only 6x%, failed
My 1st car 10 years ago agent free tint. Low quality brand and fully compliance JPJ. My customer from Europe come sit in my car sweat till ketiak wet.
Then I go tint 35% vlt all sides with 90% IR. Quite good. But I always go out at night clubbing. Police kacau few times. Say tint dark, cannot see inside if no wear seatbelt or play handphone police cannot see. Die die ask rm50 kopi.
JPJ so far didn't kena before. But only heard need to tear off if roadblock and go JPJ inspection. Money not issue, is the time to go do this and that.
