I had my company service car (2005 Altis) tinted with Vkool OEM 5 and OEM 35 on the windshield, so far I'm very happy with the tint, mas maganda talaga heat rejection compared to other tints na nasubukan ko (3M, Solargard, Platinum). Tried parking the car under the sun during noon time for about an hour at pagbalik ko hindi gaanong mainit ang loob ng car. Ang mali ko lang yung pinili ko na OEM 35 for the windshield, ok heat rejection nya pero kitang kita ako from the outside, should have gone with OEM 20 for the windshield, pero pinapatungan ko na lang ng 3M FX-ST 35, so ngayon ok na ko with the windshield.
