Interesting 2 videos I came across by accident. Makes logical sense to me and less flaffing about with buckets. Will obviously need one for wheels though. I have been using the multi mitt method for a while now, but just couldnt get enough soap down. This seems the solution to replace the bucket but still use the multi mitt method. I would still snow foam the car first as usual though. An alternative to using the foam for the shampoo is to mix the shampoo in a spray bottle (Car Craft Auto Detailing) - again probably even easier than the above with multi mitts and dare I say both safer on the paint ?
