Good camera angles on his videos, can actually see what's going on. I thoroughly bored my other half watching it on the TV last night!
My previous Z4 looked similar to his in condition but I was able to achieve about 80-90% of his finish myself in a day and a half. It's not difficult, just time consuming.
I draw the line before a company like his does as it's very much a law of diminishing returns. Life's too short to polish door shuts in my spare time. I shelled out £450 for all my cleaning goodies but this included £100 on a Sidekick Blaster (glorified hair dryer) and snow foam gear as well as the polishing stuff. However, I've now done two cars with it and will do my C63 in the Spring and any future cars for very little further outlay.
Quite enjoyed his videos! I thought his changing of the badges was a good move: mine too had started to look a little chipped at the edges and the new ones in the video really made a difference I thought.
