This primer is one of the best because it works well and works on most metal surfaces.įor best results, the primer should be applied in 2 coats before applying the top paint. It’s oil-based and comes in one color choice. The metal primer is a paint and rust converter in one. Any surface that would not hold up to this prep work should be treated through another process. In order for the primer to be applied, the surface has to be cleaned of loose rust and washed. The Rust-Oleum Rusty Metal Primer is used on moderately to heavily rusted items that are in good structural standing. Where these two products differ is the degree of corrosion of the object and the follow-up steps. The new surface is then clean and ready to be painted. As converters, they convert the rust into a more stable surface by stopping the oxidation process. These two products from Rust-Oleum essentially do the same job. These converters don’t add support to an item. When using to restore furniture, make sure the furniture still has structural integrity.

Professionals use them to restore historical items, staircases, fencing, and outdoor furniture. Metals in this class include:Ī rust converter will be used to save a wide variety of objects and structures. Other metals that resist oxidation include titanium, niobium, and tantalum.īase metals are the opposite and are prone to corrosion. Noble metals are the most notable, which include gold, platinum, silver, palladium, and more.

Oxidation occurs most commonly on steel, but some metals resist oxidation. Oxidation is a chemical reaction of the surface of metal. Rust occurs through a process called oxidation. Essentially, what this means is they don’t remove the rust but convert it from iron oxide to iron tannate. Products like the Rusty Metal Primer and Rust Reformer are considered rust converters.
