Having it on the car for the first time, I wouldn't really say it makes a lot of difference and probably wouldn't waste my money on it again...
Dealer's going to do it at cost, which is £200, for paint seal and leather stuff. Did not realise it but I had something similar on my 996 T, it was slightly noticeable and actually didn't need to wax as much.
