Yes I agree Vkool is the best in terms of lasting heat rejection and clarity and zero issues of film quality. Only downside is interfering with GPS last time... but I don’t use standalone gos anymore.
I didn’t use vkool this time bec I was quoted $1400 for my car... went 3M crystalline range for $1000 but I think was far from vkool... wouldn’t use that again. Went for zen at $430 and I think same same as 3M.
Next time I tint.. will either go for $400-500 film or vkool. No more those $800-1000 range..
Not sure why again on so-called top of the range 3M crystalline version ... BIL collected his X3 and already find 3M crystalline provided foc by Performance Motors cannot make it and looking to added 2nd layer like you and me.
For the last 1 month +, absolutely ok and without any major discomfort despite the hot weather and bright sun which make my sgd350 of Zen film on front windscreen and front side window one of the best spent.
