Does factory tint block heat?
Most of the factory tint on the clear glass is roughly seventy percent visible light transmission (VLT) and rear factory tint on many trucks and SUVs is roughly at twenty percent VLT. The heat and UV rejections on many factory tints are limited. You can boost the performance of the factory tint without making them noticeably darker by adding a 70% virtually clear or 50% slightly tinted tint on top of the factory tint. On the other hand if you like more privacy, you can choose to add a darker tint. If you add a 35% tint on top of the factory 20% tint for example, it will end up at roughly 7%. The equation is 35 x 20/100 = 7% VLT.
