Rust-Oleum Universal Bonding Primer Spray Paint (White) Rust-oleum universal bonding primer is a fast dry, maximum adhesion white primer that firmly bonds any topcoat to difficult-to-paint surfaces, including two part epoxies. It may be used on interior or exterior surfaces to include galvanized steel, wrought iron railings, furniture, aluminium flashings, PVC, porcelain, masonry, glazed brick, metal, wood, fiberglass and other surfaces. Universal bonding primer features an advanced spray system that allows you to spray at any angle, even upside down for those hard to reach areas. A comfort spray tip with a wider finger pad reduces fatigue caused by continuous spraying. For more information, visit the parent website of rust-oleum.
