Unlike most other aerosol paints, each Preval Power Unit uses just 1.97oz.
of eco-friendly propellant to spray up to 16oz. of liquid. What's more,
each versatile Preval unit can be used with different formulas for
different projects. Ideal for in-the field touch-ups, every Preval Power
Unit secures to a recyclable glass bottle and atomizes virtually any
color-matched paint, formula or solution with consistent results.
