Storage Seal Rust Inhibitor

Mercury Storage Seal forms a protective barrier that prevents rust on internal metal surfaces. It also keeps cylinders lubricated to prevent cylinder or piston damage when starting your engine after storage.
Use in all 2‑ and 4‑cycle carbureted and fuel‑injected gasoline engines including cars, trucks, motorcycles, ATVs, snowmobiles, marine engines, lawn mowers, chain saws, string trimmers and snow blowers. 
Safe for catalyzed engines.
