Hi, The darkest you can go in the front is 28%, it doesn't matter how dark in the rear, but with millennium they only make 18% as the darkest film. laura's car is 28% all around the same as mine , but it's up to you!. it takes 1/2 day to do a car with out rushing as I usually have 10 to 15 cars to do every day. i don't like to post pricing on the net but don't worry I will give you guys a special deal ( cheaper than what I charge my car dealers )Millennium film is very expensive and is the best film available on the market today @ I will look like an idiot to my fellow tinters if they see what I charge you guys for high end film. so give me a call or stop by and check us out. thanks Sean
