TRIO-RUCON-X is a chemical substance that converts rust (iron oxide) into a primer by applying it to rusty surfaces with its special formulation. The product is not a rust remover, it is a rust converter. It is formed in rust layers and must be disposed of before many operations. Sanding, wire rubbing, scraping may not completely remove rust and may cause corrosion under the new paint film. However, TRIO-RUCON-X ensures that the rust formed is completely transformed into a primer and prevents the formation of new rust. The forward formula neutralizes rust to form a protective layer and stop corrosion.
