Hi; The commercial unit showed up at my place ,contained on a car trailer, compressor and all. Hooked up to my water hose and wet-blasted a '39 cpe shell in my gravel yard. One yr later no rust as I work on that shell, inside. I posted it on an old thread here. they used a rust inhibitor in the mix and the sand went into my gravel. Newc
