Don't be tight with tints, it's worth paying the extra, otherwise you end up with nasty purple tint film and more bubbles than an Aero bar. Worth a try is Tint Master in Telford. http://www.stripemaster.co.uk/
Bought: Obtain in exchange for payment. Brought: Come to a place with (someone or something).
These words are NOT interchangable....!
Why not just buy the pre-cut stuff... all you need is a squeegy and some water mixed with some washing up liquid... it's very easy, and if you are carefull, can look very good...
I tinted an old Cavalier, and the result was quite good... hardest part was cutting to size (which was also the part that looked worst) no air bubbles though...
