I just haven't figured it out yet. I'm sure I'm not the only one that has noticed that once a sticker has been on the inside of an 80 with the factory tint for a while, when it is removed, the glass looks different. See pics. This 97 FZJ80 had stickers on the INSIDE of the windows and were removed. It looks to me like there is some sort of coating on the inside of the window that came off with the sticker. The previous owner owned this vehicle for about 14 years so the stickers could have been on there for all or part of that. To my eye, it looks like this "tint" is not in the glass as has been speculated, but rather on it (inside), and so therefore there must be a way to remove it. Right? I mean, besides replacing all the glass or covering every square inch of it with stickers for 14 years and then removing. If there is a way, it may also apply to the early 100 Series which look to have a similar tint from the factory. Again, I can tell that the discoloration happened on the inside of the glass. This pic on top looks like it maybe had one of those vinyl static clingy stickers and it wasnt firmly pressed onto the glass on the bottom. Whatever sticker was on the bottom pic was firmly pressed on. I just saw this and it got me thinking. These are the kinds of things I think about when driving by myself.... Any ideas from anyone on this? I know I'm not the only that likes clear glass, or at least all the glass to match if I want to do some tint.
