It works on both rusted and clean metal, bonds to the substrate, and cures to a long-lasting metallic gray surface that resists chipping, chemicals, and sun fading. The product is formulated for brush, roll, or spray application and is intended for repair, restoration, and preventative maintenance on automotive and industrial metal parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does RUST BULLET stop rust and protect metal surfaces?\u003c\/h3\u003e\n\n\u003cp\u003eRUST BULLET bonds to metal and encapsulates rust, forming a dense barrier that isolates corrosion from oxygen and moisture.
