APOC 291 Rust Prep Rust Inhibiting Acrylic Primer, Red, 5 Gal
APOC 291 RUST PREP is a high-performance acrylic rust-inhibiting primer for ferrous metals, sold as a 5-gallon pail and drying to a red finish. It stops existing rust, seals corrosion against moisture, sun, water and salt, and creates an ideal base coat for any APOC paint or roof coating. Apply your topcoat directly over the primed surface.
Key Features:
- Stops rust formation: The acrylic formulation inhibits corrosion on ferrous metals and permanently seals existing rust.
- Corrosion resistant seal: Creates a corrosion resistant barrier that protects against moisture infiltration and weathering from sun, water, salt and oxidation.
- Improves adhesion: Bonds to difficult substrates and prepares surfaces for reflective coatings and topcoats.
- Ideal base coat: Dries to a red finish that serves as an ideal base for any APOC paint or coating.
- Wide substrate range: Suitable for metal roofing, window frames, sidewalls, rail cars, pipes, equipment, tank exteriors and structural steel.
- Topcoat ready: Topcoat can be applied directly to the primed surface once dry.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Rust-inhibiting primers like APOC 291 are the critical first step on any rusty metal roof or structural steel before a reflective or elastomeric coating. Remove loose scale and debris first, prime bare and rusted areas, then topcoat directly over the red-primed surface. Choose this primer whenever ferrous metal shows oxidation or when the coating manufacturer calls for a corrosion-resistant base coat.
Apply in a well-ventilated area and follow the product label and local codes when working on metal roofing or elevated structures.
