Tuff-Boy Quick Dry Low VOC Rust Stop Primers are durable products formulated with modified alkyd resins and rust inhibitive pigments to give outstanding corrosion protection on ferrous metal surfaces. These fast drying products have unique surface wetting properties that make it possible to prime ferrous metal surfaces where thorough cleaning and sandblasting are not possible. The tough, durable film will provide sufficient resistance to weathering for a period of up to 6 months before enclosure or topcoating. These primers contain no lead or chromate pigments.
