FERTAN Rust Removal & Prevention: How To Remove Rust From Your Car (Underbody, Trunk, Doors) 

When I mentioned "this process should settle the rust issues for the next 4-5 years," I meant that using FERTAN Rust Converter can provide long-lasting protection. FERTAN penetrates and converts rust into a stable compound, creating a protective layer that prevents further rusting. With proper application and maintenance, this treatment can effectively prevent rust from coming back, potentially lasting even longer than 4-5 years. Regular maintenance and protective coatings can extend this duration significantly.
