can anyone who has tinted there windows on a ford focus tell me how hard (or hopefully eaSY) it is? and also any other tips and tricks for enhancing the look of my 57 plate focus?

there are lots of good videos (youtube etc) showing the techniques involved.
It looks easy on the videos, but I've never done it, so I cant say for sure. Its probably a lot harder than it looks.

Personally, unless the front windows are also tinted to match the rears (which is of course illegal) then I think a half-tinted car looks odd and unbalanced. I would leave it alone, but its all a matter of taste of course.

get it done professionally.. definitely worth the money, rather than doing it yourself an having bubbles everywhere, an it peeling! most of them come with some sort of warranty an that.. cost around £130 tho..

Yea get it done professionally, looks a lot better might cost a bit more but worth the extra few quid.

yeah got quoted 110 for it? like the tinted windows there good for the wane in the back and stop the glare more a case of practicality as much as styling tho.

Dont forget they also have an effect on seeing out at night. Looking at your rear view mirror through a dark tinted rear screen is pretty dark.

its not too bad had the black tint on my mazda 6 sport and didnt have any trouble with that?
