I've searched around online, appears like you can use an Aluminum Brightener on non-polished Alum. to make it appear new again. I tried this on some parts - skid, rock sliders, A-arm guards & wow what a difference. They really do look new again..
Question - has anyone used this on the engine/transmission cases? Will it harm the rubber hoses, wires?
