How long does the rust conversion take?

Once the area is saturated with formula, allow 15–30 minutes for a standard surface conversion.

How much surface area will one bottle cover?

Approximately 120–150 sq. ft.

Once converted, do I need to rinse off the surface?

Yes. Once converted, use clean water to rinse the area and allow it to completely dry before applying a coating.

How do I know it’s working?

The rusted area will begin to bubble and turn a gray/black/dark blue color as the rust is being converted.

Do I need any special tools to apply it?

You'll need acid-resistant materials like gloves and safety glasses, along with brushes to agitate the area.

What if the rust is heavy in one area?

Remove loose rust with a wire brush first, then apply the product. You may need to apply it twice in areas of heavy rust so the formula can fully penetrate the metal. A gummy residue may be left behind; rinse it off during the clean wash process prior to coating.

Rust Converter

$29.00

Stop corrosion on your RV frame and undercarriage with a safe, non-toxic liquid converter that conditions rust into a paint-ready protective barrier.

Features & Benefits

Eliminates Hard Labor: Chemically converts rust into a stable iron phosphate layer—no tedious grinding, sandblasting, or heavy wire-wheeling required.
Treats Hard-to-Reach Crevices: Penetrates deep into chassis seams, pitted metal, and hidden frame joints where mechanical tools can’t reach.
Stops Active Rust Permanently: Neutralizes corrosion at the chemical level so rust won’t continue eating away at your vehicle under your new coat of paint.

Size: 32 oz Bottle

Road Guard Rust Converter is a safe, non-toxic, and non-flammable liquid phosphoric acid formulation that effectively conditions rust. In addition to treating rust and corrosion, it removes oil and can assist in stripping existing coatings or paint. This converts the rust itself into a primer-like layer rather than requiring you to remove every trace of it. It begins working immediately to transform rust into gray/black iron phosphate, effectively interrupting the rusting process. The converted layer provides good adhesion for primer and topcoat, especially compared to painting over untreated rust (which will continue to corrode underneath and cause paint failure).

Features & Benefits:

Save Time & Labor — Less grinding, sanding or blasting.
Reaches Inaccessible Corrosion — Works on rust in crevices, seams, and pitted areas where mechanical abrasion tools can’t fully access.
Stops Active Corrosion — Chemically neutralizing the rust, it halts the oxidation process rather than just covering it up.
Creates A Stable Painting Surface — The converted layer is typically black or dark bluish and provides good adhesion for primer and topcoat, especially compared to painting over untreated rust (which will continue to corrode underneath and cause paint failure).
Cost-Effective — Cheaper than abrasive blasting equipment or extensive labor-intensive surface prep, particularly for large or numerous rusted items (attachments, equipment, or vehicle frames).
Reduces Risk Of Missed Spots — Since it’s applied as a liquid, it can penetrate and treat rust in areas a wire wheel or sandpaper might skip.
