• RUST CONVERTING TECHNOLOGY - Chemically reacts with rust at the molecular level to transform it into a stable, protective layer, preventing further corrosion and extending vehicle life.
• SALT & BRINE BARRIER - Creates a powerful grease shield against road salts and brine solutions, the primary causes of undercarriage corrosion, especially during harsh winter conditions.
• PASSIVATION PROTECTION - Goes beyond surface sealing by passivating metal surfaces to neutralize corrosion activity while forming a durable protective coating for long-lasting defense.
• EASY APPLICATION - Virtually odorless oil formula applies smoothly and sets quickly. Simple three-step process: remove loose rust, rinse with Salts Gone, then apply Under Gone.
• VERSATILE PROTECTION - Ideal for all vehicle types including daily drivers, work trucks, SUVs, trailers, off-road vehicles, and classic cars, trusted by fleet operators and automotive professionals alike.
