Rust Inhibitors For Direct To Metal Coating Preparation

Rust inhibitors

When you are preparing a metal surface for an exterior painting or coating project, Rhino Shield suggests using our red oxide metal primer to get the best results for your DFCs topcoat and overall. This primer is designed to prepare metals like steel and aluminum for coatings and help encapsulate existing rust. Our red oxide metal primer is very high in solids, including zinc and red iron oxide pigments. Red oxide is more environmentally friendly than traditional red iron oxide formulas, making it the perfect choice for those who want to stay as green as possible when it comes to their exterior painting and coatings. Rhino Shield's red oxide metal primer is classified as a water-based, direct-to-metal primer.
