Eastwood Fast Etch Rust Dissolver - 1 Gallon
Product Review (submitted on November 22, 2010):
We routinely use this on bare metal parts to protect them until we can paint them. We used this product on steel fenders after they came back from being chemically stripped. It was over two years from when the fenders were stripped until they were ready for paint and no sign of surface rust. We always keep some on hand.
