Mike, Thank you so much. The article was great and just what I wanted to read. I have the Klasse and D151 and like both. Mainly wanted something more aggressive than the Klasse and longer lasting than the 151. Thought the XMT 360 might just fit the bill so I will order some. This may sound crazy to some but I do this for the fun and gratification, the money is secondary. I need to get paid but sometimes I do it for less money especially when the person can't afford as much as others. I started fifty years ago part time, at 13 yrs. and have been passionate ever since trying every product available. I have enough Wolfgang on hand to do dozens of vehicles. I am currently building a dedicated, as you say surgically clean, shop for two vehicles at a time. Looking for some steel cabinets to store my towels and supplies in and one side will be for washing and cleaning with a drain in the floor. Thank you and all the others on the forum and Autogeek.net for hours of enjoyment and it just shows that an old man can still learn new things if he just opens his mind to new ideas. Your videos are great!
