You put sunscreen on yourself to protect your skin from the harmful uv rays, but all you need to do is install window film by The Tint Pros that will block 99.9% of the UVA and UVB rays from entering your car, home, or office. SPF in sunscreen is no where near the SPF number you reach by permanently installing tint. TTP has tint that blocks 99.9% of the UV rays and 44% of the heat while having a virtually clear appearance. Dont’ be fooled by some company’s false or tricky marketing, trust the PROS, we have been doing this since 1979 and only offering the best product, best service, and best installation. Don’t forget, our film is also skin cancer foundation certified!!
