It all depends how dark you want it. I would go for dark smoke 20% VLT on the rear window and rear side windows and 1 lighter on the front 2 windows. If you wanted to stay on the right side of the law then nothing on the front 2. Your looking at about £100-£130 ish for the full car. I used to do them myself but they are a nightmare so stopped and just take it to the tint shop to get them done. Ive used AES in oldbury as I know him but his job isnt too good. There is one other place which is in Handsworth where I go to now called Sunset Tints just by the hockley flyover. Also another place by West Bromwich which is also good. Hope that helps.
