NO SCUM buildup in expensive blasting equipment, even with use of hard water. With Tank Volume Indicator.

As a surface passivator, HOLD*BLAST™ chemically changes the active surface of metal to a much less reactive state. Surface corrosion can occur when water wet surfaces react with atmospheric oxygen. This often results in the formation of flash rust, which can be eliminated with the use of HOLD*BLAST™. This product passivates the surface to stop the formation of surface rust for long periods of time, often several days.
