Rust-Block is a new product that will coat the metal with a non-sticky coating that inhibits rust from forming up to 6-months. Just like Evapo-Rust, Rust-Block is safe on all metals, biodegradeable  and has no harmful fumes. Just spray on and when you're ready to paint or finish your metal item, just rinse off with warm soapy water or follow your normal paint prep procedures.  Store your protected item indoors! This is a water-based product that will be rinsed off by rain/outdoor weather. Comes in a 16-oz. spray bottle. This product is proudly made in the USA.
