For the U.S. crowd, Wurth is a German manufacturer. Their promary line is fasteners, but they handle a lot of chemical stuff. Very pricey. For instance a rattle can of their wheel paint retails at about $20.00, I have seen it on the 'Net for about $15.00. Its only advantage is that it matches the silver on almost all Euro alloy car wheels, Audi, Mercedes, Volvo, etc. So, figuring 3 cans of paint and 2 of clear, you are looking at about $100.00 to paint a set of wheels. Although the ads talk about "fine German nozzles", my only interest is the color.
