Noooooooooooo, dont pay £80 mate!!!

I used to do loads of these at work and a few of my own cars. All you need is a new stanley knife blade and a spray bottle with a fairly liquid/water mix in it. Start to peel the film off and once its all off, youll be left with a clear film of glue. spray the mixture on and itll come off easily with the blade. Its sometimes easier to peel the film off if you point the heater vents to the window for a few minutes first.

Should take no more than about 10-15 minutes MAX to do two front windows.

By the way, its the rear windows that are a pain with the heated elements in. Best to use a tar and glue remover on the rears.
