Wow some serious skills involved in that. Does show the main reason why I personally wouldnt get it done on my daily driver though, finishing at the edges. They mainly just tuck a tiny bit behind the edge, and I'm yet to be convinced that will to the distance. I know they dont tuck a load behind it as its easier (and cheaper) to cut it and tuck a little bit, but for me to trust it I would want a decent amount folded behind each edge, and windows removed, lights out etc to get in properly. But that would cost too much
