window tint question

[kirbster]

The previous owner of my car put 5% all around. It looked good but I got tired not being able to see out the back window at night. So I took it all off.

Had the windows re-tinted 35/20. Still not real happy with the back glass. At night light will "refract" from the defrosters. So when I look at my rear view mirror it looks like a bunch of lines of light...There is also a lot of reflection during the day. Anyone else experience this?

My tint is 3M FX Premium. I wonder if a different type of tint or darker/lighter would have been better?
