It also inhibits rust formation when applied over clean ferrous metals like iron and steel, eliminating the need for a separate rust-inhibitive primer. The formula dries to a smooth, tight film that resists flash rusting and long-term rust development, making it i for priming metalwork such as iron railings, steel doors, and metal panels. Suitable for use under or over oil or water-based paints, this water-based primer features a low odor and easy soap and water cleanup. It can be tinted with many universal colorants, and the gray version is for use with rich or dark topcoat colors to improve coverage and hide.
