After following and reading this thread since V1 Pg. 60 onwards. My 2 cents on top 3 BEST Tint in No particular order.

1) Huper Optik C70 front and Back and C40 side

2) Raytech Centurion 4 mil OR 6 mil.
Budget Alternative CS85 5 mil. OR CS75 4 mil.
- 7 years warranty is a Bonus. They have Complete range to suit your budget.

3) 3M Nano 70S with Crystalline 70 front.

OTHER Brand/tint?
Proceed with caution. Avoid Groupon/Webuy/Ilovediscounts tints as they have Hidden costs or they will MAKE you upgrade for better quality tint. One customer ended up paying RM688 instead of RM288 cause is D-segment car and sweet-talked to upgrade to Higher quality IRR tint). Good thing no cheap.

These above 3's ENDORSED and Highly recommended by my Customers. (I sell new cars). V-kool standard dropped and COST very high. Llumar is Good but MANY Imitations.
