Well I went to www.rustoleum.com and they gave me a choice between the U.S. and Canada sites-
so I went Canadian and they list Tremclad, so it is a Rustoleum Canadian product.
Now who knows how this translates down in the U.S. of A.? But I'm sure with some e mails and/ or toll free number research w/ the rustoleum company, this can be determined!
