I have just redone the small rear side window on the Firenza. I bought some new Defender window tint from Halfords thing that it would be better than what was left under the bed. Wrong the Defender stuff was totally rubbish, i thought it was me but the stuff would not stick and was *Bleep* to work with. I tried the old roll which is Eclipse and it went on easy as 123.
Just thought it worth mentioning as its not cheap stuff to waste.
