I did a Yahoo poll on what people's opinion is on window tinting. You might want to check it out if you haven't already. I was planning on using the mirrored film, but ended up using black. The installer told me that older cars and cars that have been previously tinted tend to show a lot of imperfections with the mirrored film (mainly as scratches). In his showroom he has a dark booth with a window covered with swatches of film. The mirrored variety was almost invisible from the inside -- meaning that it was hard to tell that it was even on the glass compared to the bare, untinted area. This was mainly due to the fact that it did not block UV very well or much visible light for that matter. (This mirror film is different from what the industry calls "limo tint" which is highly reflective and illegal to use on front windows.) Of all the varieties he had, I liked the black the best (and that is what he liked best too), so that is what I had him use. The brand I'm talking about is Llummar. He demonstrated 3 basic varieties: black, charcoal & mirror in different percentages of darkness. (The mirror tint only came in one shade since it works by reflection and not absorption.) I ended up tinting the quarter panel windows and leaving the rear window untinted. Another option was tinting both the rear window and quarter panel windows with something lighter so that looking through both pieces of glass wouldn't be too dark, but that would have looked slightly uneven from the outside and the combined darkness would have restricted visibility too much for my tastes. If you are using mirrored tint, it would be wasted on the back window because this stuff depends on reflected light to make it hard to see in. With the rear louvers, there wouldn't be much light to reflect. It also doesn't do much at night (meaning that people can still see you in the car.) It would be interesting to see a brand that combines mirror tint with UV metallic but Llummar doesn't make it. I used my car for a while with only the drivers side tinted from the previous owner, but I removed it all from the passenger side. It was interesting driving around seeing the difference. I much prefer the DeLorean with tinted windows because then all the gawkers can't tell when I notice them. Then they point and stare without inhibition. But if they know I'm aware of them then they usually try to play it cool. From the inside, the tint is more noticeable in daylight, and at night there was very little difference. People argue that window tint isn't safe at night, and to that I can say that what is legal for the front windows is fine, but any darker is too dark to be safe at night. When I had the new film put on the passenger side, I left the driver's side for until I can get around to re-gluing the window frame that is slightly loose. The new film is a nice improvement since it is a metallic film that blocks UV instead of the old film that uses dye pigments that tend to bleach out to a purple color with continued sun exposure. It will be interesting to see what shows up at Memphis. I'm bringing my camera. Walt Tampa, FL
