Formula
Original Oil: our flagship, proven on any vehicle. V3: an oil, wax and lanolin hybrid with a drip-free formula.
Color
Clear leaves surfaces looking natural. Black adds a biodegradable tint for a clean underbody finish.
Size
1 or 5 gallons. Not sure how much you need? Contact us and we’ll recommend a size.
How to Use It
- Prep: pressure wash heavy mud or flaky rust, ideally a day ahead. Dry is ideal; damp is OK; avoid heavy rain. Make all electrical connections first.
- Spray: work the wand into the frame, wheel wells, rocker panels and door cavities, where corrosion starts.
- Avoid: keep it off brakes, exhaust systems and soft rubber molding.
- Maintain: reapply once a year and keep high-wear spots topped up.
