Looking to tint your car windows yourself? This SW nano ceramic film is a professional-grade option sold as a big 60-inch by 16.5-foot roll, giving you plenty of material for multiple windows or a few cars. It's a 2-mil thick, 2-ply PET film with a scratch-resistant coating. The key specs: it blocks 99% of harmful UV rays (protects your skin and your car's interior), allows 80% of visible light through (VLT), so it's quite transparent and legal in many places, and it rejects a high percentage of infrared heat (90-95% IR rejection). It's non-metallized, so it won't interfere with radio, GPS, or cell phone signals. It also helps reduce glare and adds shatter-proof safety to your glass. Installation requires some patience and soapy water – the instructions are included. A great DIY project for improving your car's comfort, privacy, and protection from the sun's heat and damaging rays.
