Yes. If, for any reason, Rust Bullet is transferred to another container; clean, unlined, metal paint cans (or similar unlined metal containers) must be used. Make sure that the container can be properly sealed. Stir the contents for at least three minutes before transferring any portion of product to a different container. Use Bloxygen to displace the oxygen with an inert gas (Argon) prior to sealing to prevent curing of previously opened containers of Rust Bullet coatings. During application, pour out the portion you will use in approximately one hour and reseal the lid as soon as possible. In all situations, you should minimize the time Rust Bullet coatings are left open and exposed to the air.
