Krown is Canada's #1 Rust Protection in a can. To protect metal from rust, a barrier must be created and maintained between the metal and the surrounding elements, especially moisture. This product is designed to create a barrier that can't be broken, chipped or cracked. By staying fluid, our petroleum based rust protection heals back over after any abrasions providing lasting protection, even in extreme conditions. Featuring inverta-spray technology, this convenient aerosol can, lets you apply our industry leading rust protection to vehicles, machinery, electrical connections and even hard to reach areas around the home and worksite.
