Hey,
Well the film itself is cheap as chips. Just need to make sure you buy one wide enough to cover the height of the windows, but that's fine.
I am in pontypridd, but my girlfriend lives in Neath, near swansea, and its really not that far from me. You have to pass me to get to swansea.
Price wise i would say that at most it would be £20 for the film, and then its just having a preferably non windy day, or at least sheltered place to do, but thats sortable.
I wouldn't charge you for doing it, as i'm not a pro. But i'd say i'm good
Have a look on ebay...measure the height of the windows, and then measure the total all around the car, not including windscreen (or the front door windows, as they aren't legally allowed, well...only if they are obvious)
And then we can order some, giving allowances for mistakes. Which although i hope dont happen, may well.
Medium tint film would look good.
Lets arrange something. I can do mine the same time then.
