Great topic, love to hear from some experienced pinheads what they think is best. used mill wax but will throw that in the trash right away. Problem is how do you get one grand blitz wax in Europe? I only see one seller on Amazon. Where do you buy that stuff? I will be heading to the US in May maybe pick up some there but before going on a wild goose chase on auto stores who will all try to sell me something similar.... Any suggestions?
