OSPHO Surface Prep Rust Converter Quart - Metal Primer for Rust Removal & Corrosion Protection - Prepares Surfaces for Paint - Durable Coating for Automotive, Industrial & Home Use

OSPHO Surface Prep is a balanced formula featuring phosphoric acid, dichromate, wetting agents, and extenders designed to prepare metal surfaces for painting. It functions as a primer, not a paint, and is ideal for applications where complete rust removal isn’t feasible. Simply remove loose paint, rust scale, dirt, oil, and grease with a wire brush before application. OSPHO converts existing rust into a stable, paintable surface, offering long-lasting corrosion protection. This quart-sized container provides ample coverage for various projects. The liquid consistency allows for easy application to intricate shapes and hard-to-reach areas; let dry completely overnight before painting. OSPHO is suitable for use on automotive parts, industrial equipment, fences, railings, and other metal surfaces prone to rust and corrosion. It's a cost-effective alternative to sandblasting or extensive rust removal. Contains approximately 32 fluid ounces (946ml). Apply at temperatures above 40°F (4°C). Ensure adequate ventilation during application and drying. Follow all safety precautions listed on the product label; always wear appropriate protective gear. The converted surface is designed to accept most topcoats, ensuring a durable and long-lasting finish. This product is a chemical conversion coating, not a paint, and offers a robust foundation for your painting projects. For optimal results, apply a second coat of OSPHO if the initial application is thin or if the rust is heavily concentrated.
