I've seen bits and pieces of info here and there but I could't find a thread that had any details/comparisons. What's the best out of the spray can metallic finish out there? I've seen the pics for the plasti-kote brilliant metallic and that looks amazing. Is there anything in North america that would produce a finish like that? Are there any other options for producing a really nice a shiny surface apart from paint, like the polishing powders i've read a bit about?
