Been doing a lot of research on this and the common opinion is that the refreshed Model X rear windows are only privacy glass and don’t provide any UV/IR rejection. Only the sun roof windows have any UV/IR rejection Has anyone ever verified this with a meter? I got quoted by a local to tint shop $3100 for full frontal xpel PPF and xpel ceramic tints. I’m on the fence of getting tints done on all windows if the rears already have some UV/IR rejection. I would only get the driver and passenger side windows done if the rears don’t need it. Also can anyone advise on if this is a good deal?
