Recently bought a new pick-up, and kept the ten yo ''Weatherguard'' toolbox from the previous truck. I'd like to spiff it up a bit to go on the new truck and I am not sure what to use to polish the aluminum box. I do not have a buffer, I need something that works well by hand application. Anybody found a product that works well? The toolbox is not raggedy, just the usual amount of oxidation dulling after 10 nears. [ Weatherguards are too expensive to buy a shiny new one ]
