    Quotes from Our Customers

    It’s no secret we’re the industry-leading solution that lasts. Here’s what our
    customers have to say.

    Because of my experience in the field with this product, I always recommend ZRC in corrosive applications. I've used ZRC to regalvanize radar towers and catwalk gratings for the Navy at the base in Winter Harbor, Maine. I also used it on metal roofs and on salt water cookers at a canning company. In all cases, it has provided five years or more of rust-free protection.
