Rust Eraser to remove rust from those unreachable places?
Widget Supply 3pc Sears Craftsman Rust Eraser Set

I haven't tried them yet. My method is to cut a pencil eraser into a shape that will fit between the scales and apply some Dupont No. 7 car polish. This takes care of superficial rust and dirt. As soon as I get to Sears, I will try their "Rust Eraser".

Has anyone tried this or a similar product?
