Chemically converts rust into an inert, black barrier on steel or iron surfaces

Restore your investments without breaking a sweat! Gempler's Rust Converter stops your tools, vehicles, tanks and other implements from further rusting. Simply use a wire brush to remove loose or layered scale and rust, then apply Rust Converter with a paint brush or sponge. Once applied, it functions as a primer and the treated surface is ready to paint with an oil-based paint in 48 hours.
