Rust-Oleum Automotive Self Etching Flat Gray Oil-based Spray primer ( NET WT. 12.0-oz )
If we remove the galvanized coating on a steel stock tank [with sandpaper and then etch with vinegar], could this primer be used under Pond Armor?

Happy to help! To ensure full adhesion, any zinc on the surface must be removed as this is what hinders full adhesion of oil-based paints, such as Rust-Oleum Automotive Self Etching Primer Spray. Please keep in mind, we do not recommend this primer for use on surfaces that will be immersed in water, as it will not hold up in that enviorment. - Rust-Oleum Product Support 3
