Anti-glare Tinted Window Film: Any experiences?

[Mervyn]

I have a 1983 W126 (280SEL). Having seen all the newer cars come with factory-fitted tinted glass, I'm thinking of getting some tinted film for a DIY job for all my front/rear windscreens and side windows. The dark look as well as the extra privacy it affords is really tempting. The upmarket brands (V-Kool, SunCool etc. are out since a complete installation cost at least USD$650).

My questions are:

1. Will these cheaper DIY films "trap" any harmful UV or infra-red rays inside the cabin? (since I do not suppose they have proper reflection properties)

2. Once I install the film, will it be permanent? If I choose to remove them in the future, will it damage the glass?

Need some advice on this, thanks in advance!
