From these i can say 90% of the tinted car in malaysia does not meet recent JPJ rules. Usually the officer will not stop you unless your tinted paper is too dark.
As long as they can see you through the mirror, you are passed.
For puspakom examination, JPJ do know your tinted paper are 90% changes does not passed their test, they will surely request you to tear it off before the test.
(Only happen if you want to sell off your vehicle)
For consumer, we concern on the below
1. TSER = Total Solar Energy Rejection (Real heat rejection) > 60%
2. IRR = 90%< Infrared Rejection <95%, don't go beyond 95%, or your GPS or Smart Tag might have issue.
3. UVR = Ultraviolet Radiation, >100, this is always more than 100, up to 400
4. Warranty, degration on TSER
5. Warranty, bubbled, how many pixer
6. Warranty, scar
7. Warranty, blur
8. Warranty, change in color
Commonly we look into these few items, how many years the tinted shop will cover for us.
Forget about the VLT, as long as they can see you through the windows during road block, you are clear to go.
In order to have a VLT really passed JPJ rules, you may need the tinted paper VLT > 90%, provided your car windows are originally 80% VLT
So long you tint within JPJ regulations and did not go into PUSPAKOM, your car tint is fine.
On the warranty issue, mostly item No.4 are subject to approval and others are claimable during warranty period.
