Brushing RustGuard™ Rust Converter onto corroded metal

Restore, don’t replace

Three steps. One durable finish.

  1. 01PrepBrush away loose flakes, dirt, oil and grease. Sound rust can stay — that is what the converter needs.
  2. 02ApplyBrush or roll an even coat over the rusted area and let the formula react.
  3. 03FinishAllow the treated surface to cure, then paint for lasting protection.

  • Saved my truck bed

    Wire-brushed the loose scale, brushed a coat on and left it overnight. Next morning it was a flat black surface that took primer without fighting me.

  • No more grinding for hours

    I restore gates and railings. This cut my prep time in half on pitted sections where the grinder just polishes the rust around.

  • Held up through the wet season

    Treated the shed roof sheets and topcoated them. Two seasons of rain later the treated panels still look the way I left them.

  • Trailer frame looks new

    Frame rails were surface-rusted everywhere. Two bottles covered the whole thing with enough left over for the tongue and jack.

    Tom V. · Hamilton, ON

  • Simple to use

    Shake, brush, wait. No mixing, no strong acid smell like the jelly products I used before.

  • Bought the 5-pack, no regrets

    Fence posts, patio furniture and a mower deck off one bundle. Ordering the workshop pack was cheaper than buying singles twice.
