RUST-AABSORB™ is a synthetic acrylic emulsion that neutralizes rust. While other treatments can only prepare a clean surface for painting, RUST-AABSORB™ transforms a rusty, scaly surface into a single inert paintable surface in one easy step. RUST-AABSORB™ is a water based solution, ready to use, non flammable, contains no lead or phosphoric acid.
