I've just spent the last 7 hours washing the car the using the Klasse All-In-One, then the SG. This was the first time i had used them and i am very impressed with the results. I think the previous owner of the car used to put it through a car wash as there were lots of very fine lines on the the paintwork all over the car. I reckon about 75% have disappeared after todays hard work.
I got mine from Autopia, and as the guys have said before it was great service, and potentially great value for money. :D
