F.y.i. guys

Vkool, Solargard and 3M Crystalline tints do have high heat rejection compared with other tints in the market. These tints however do not reject all the heat inside your car, there is no such tint that does that.

Reason I'm explaining is that we have encountered some customers that complain why is it when they leave their cars outside, they could still feel the heat when they enter. This is really got to do with Physics as the ceiling (roof) of the cars have not been tinted or insulated, so being exposed directly under the sun, the alloy used in making our cars, absorb heat and hence penetrates to the car's interior.

Glass also among several factors, tends to absorb some heat hence part of the heat comes from the glass too. What tints do is that they block the direct heat or the sting of the sun on our skin or the dashboard etc. for that particular moment until ofcourse the glass starts heating on a certain spot for some time.

Hope this explanation helps those that have a high expectation that your cars will remain 100% cool after being under the sun - also considering this year's summer temp beats all other years record.
