Tinted windows??
I was going to ask the girl who did my Stealth (she did a great job- took a while to heat stretch/shrink the tint, but that's to be expected) about doing my Scamp, but I never did.
A good tinter (and I mean good with the heat gun) should be able to do it, but I bet they'd have to mold the tint to the inside of the glass, instead of the outside like they usually do. Therefore, taking it out would pretty much be a must.
The sides would be a piece of cake, being flat glass.
When I did my Duster years ago, I did the rear window in horizontal strips- there's alway that, but it's nowhere near as nice as a well-done heatshrunk piece.
btw, I took the rear window out of my '66 mustang way back when to tint it, and it does make it a whole lot easier.
