Undercarriage
Coatings
At Pro-Clean we believe in total car care. At the base of that is what everything rides on; Your undercarriage! We offer 2 options for undercarriage coatings to keep your vehicle running rust free for years to come.
Option 1 - Fluid Film Coating
Fluid Film Undercoating has been the go to favorite for fleet and government operations for decades. This Oil coating is sprayed on the entire undercoating and creates a barrier that helps keep moisture and salt contaminants from contacting the metal. The coating leaves a colorless shine on the underside of your vehicle that does wear off over time. Lasts about 1 year.
Option 2 - Under gone Premium Undercoating
Under gone is our Premium undercoating option. It doesn’t just coat over rust — it chemically converts iron oxide into a stable, inert compound, then seals and protects the surface with a durable calcium sulfonate barrier. One product. Real protection.

Rust Converting Technology
Powered by a unique corrosion-correcting formula, Under Gone™ reacts with rust at the chemical level, converting it into a stable, inert compound. -
Salt & Brine Barrier
Stops the #1 cause of corrosion: soluble chlorides from road salts and brine. Creates a tough barrier between your vehicle’s metal and the elements. -
Advanced Adhesion & Longevity
Formulated with overbased calcium sulfonate that bonds tightly to metal surfaces for long-lasting, durable protection that won’t peel or flake -
Passivation & Protection
Goes beyond sealing — passivates the metal to halt corrosion activity and create a chemically inert surface that resists future oxidation. -
Under Gone is a black self healing finish that goes on thicker then fluid film and remains flexible. It does not harden which means it won't crack or flake off over time. Undergone lasts several years and we recommend simply getting it touched up annually.
