1) I would like to know what the tint is on the rear view mirror.
I don't know if it's just shaded glass or has tint film on it, but I need to know what percentage it is. The reason why I am asking is because I own an SUV, the back window is 20% from the factory (I've been told all SUVs had 20% "privacy" glass on back. I put 5% on the back window and it's great during the day but at night I can't see anything.
I asked the SUV forum I belong to and a guy there said that he put 20% over the back window (which also had the 20% factory shaded glass) and he told me he can see just fine when looking back at night and furthermore he said he does not need to use the dimmer on this rear view mirror.
2) My second question is, what percentage should I put over the back window? 20%, 35%, or 50%? I was thinking of going with 50% but he told me that would be a waste. However, here is the breakdown
20% x 50% = 10%
20% x 35% = 7%
20% x 20% = 4%
20% x 5% = 1%
So from doing the math he claims that by putting 20% on the back window he could see fine, but this brought the amount of light in by 3% which is really nothing.
3) What percentage tint, if put over the factory 20%, will still allow me to see perfectly at night? Right now with the 5% it's pitch black at night.
35% over privacy is the darkest I would ever go, even that can be hard to see out of if the area is not well lit.
