What is the best type of surface on which to paint Rust Bullet®?
Rust Bullet® protects iron, steel and most other metals. Rust Bullet® also provides excellent protection for concrete, wood, fiberglass, and many other surfaces. Painted surfaces should be tested on a small area for lifting or cracking. Rust Bullet® is resistant to acid splash and chemical solvents. Rust Bullet® applies directly over rusty and clean surfaces providing permanent rust protection with phenomenal adhesion.
