I have a 2010 Silver Prius with limo tint which is 5%. The front brow goes down about 1/3 the length of the front windshield. I considered initially tinting the front windshield as well but did not b/c I have to put stickers and etc on the glass so I didn't want random adhesive sticking to the tint, so I opted for the brow. The brow is 5% as well. The Prius has too many windows and just lets in too much light. With the 5% it will protect my leather interior and also keeps the car cool in general, with summer coming up. These pictures were taken in broad daylight so there was not a cloud in the sky.
