Rust-oleum 3575402 Rust Converter 1 Gallon

Product Description

The RUST-OLEUM 3575402 is a 1-gallon rust converter formulated to chemically react with iron oxide on ferrous metal surfaces, stopping active rust and priming the surface for topcoating. The converter penetrates rusted areas and transforms rust into a stable, paintable base without requiring full removal of existing corrosion. It delivers 590 to 1,175 square feet per gallon of coverage depending on surface condition. Tack-free dry time is 40 minutes, with full dry achieved in 1 hour under normal conditions. This product is used by maintenance professionals, industrial painters, contractors, and experienced tradespeople working on metal structures, equipment, and components.

This rust converter is suited for use on rusted ferrous metal surfaces in both residential and light commercial maintenance applications. Typical uses include structural steel, metal fencing, tanks, pipes, and equipment frames where sandblasting or full mechanical rust removal is not practical. It is applied directly over rusted areas as a surface prep step before applying a compatible topcoat. The wide coverage range reflects performance variation based on surface porosity and degree of rust.

Key Features

• Converts active rust on ferrous metal surfaces into a stable, paintable base
• Coverage of 590 to 1,175 square feet per gallon depending on surface condition
• Tack-free in 40 minutes, full dry in 1 hour
• 1-gallon container suitable for medium to large surface areas
• Eliminates the need for complete mechanical rust removal before topcoating

Compatibility

Designed for use on rusted ferrous metal surfaces as an OEM-style rust treatment and primer base prior to topcoat application.

Installation Notes

Application is typically performed by maintenance painters, industrial coatings contractors, or qualified tradespeople familiar with surface prep and coating systems. Remove loose, flaking rust and contaminants such as grease or oil before applying. Allow full dry time before applying a compatible topcoat. Work in adequate ventilation and follow applicable safety data sheet guidance for handling and disposal.
