Kana Laboratories’ Exrust rust removing concentrate dissolves rust without damaging metal surfaces, the company says. The formula can be applied directly or diluted for use as an immersion to prepare any metal surface for painting or coating. Exrust is available in one-, five-, 15- and 55-gallon containers. A one-pint trial size is also available.
