Has anyone used or have any experience with the Dupli-Color Paint Shop Line of paints? It's supposedly pre-mixed and ready to spray in various colors. I need to put some paint on my rig so the exposed tube won't rust, but a couple of hundred bucks for a gallon of automotive paint isn't in the budget. But about a hundred bucks for a gallon of this stuff can work, even if it has to be redone in a couple of years from now is ok. Besides we all know how these things get beat up. Just wondering how well it goes on, how it looked, and how it last.......reasonably?. I don't want it to look like a rattle can, but it doesnt have to look lke a show rig either.
