Originally posted by RadMarv Before making a snap decision to just quickly go to your nearest local tint shop to have your car tinted, I suggest that you do some research and decide which type/brand of tint you want to use. Most tint dealers/installers carry only very specific brands, not all of them. Some brands of tint are difficult to find locally and may not be found in many states. Every brand of tint has different colors, compositions, characteristics, heat rejection, reflectiveness and visable light transmission(VLT=DARKNESS). Nearly all give 99% UV protection. Warranties differ greatly too. And watch out for those! You may get one with a lifetime warranty against FADING but not COLOR CHANGE. Every state has its own tint law regarding how every window can or cannot be tinted. Most state laws limit the amount of reflectiveness and VLT allowed on the front side windows, the back side windows and the rear window. Solar Gard has a very nice State Tint Law chart(Adobe Acrobat Reader required). View State Tint Law chart To find out more about tinting check out these links...

You should also go and check out your dealers/installers and actually view the tints and their work. Finally, Enjoy your research! Have fun! And enjoy your newly tinted Prius!
