*qwerty- ok na ok yung v-kool sa visibility kahit yung darkest shade nila (may mga auto kasi dun sa shop na naka-vkool pinatesting sa akin nung brand manager nila hehehe)... hindi ka kita sa labas, pero kitang kita mo ang labas from inside the cabin.. tsaka totoo talaga yung heat rejection capabilities nung v-kool... kahit yung OEM series lang nila panalo.
It's best to test dark tints at night, it will always look clear from the inside when testing during the day. Even better is to test at night during heavy rain.
