Steel shot or other abrasives that do not produce an angular profile shall not be used. After blast cleaning, and before the first coat of paint, and in any case prior to the deposition of moisture, contaminants, or corrosion, clean all surfaces of dust and abrasive particles by brush, vacuum cleaner, and/or blown down with clean, dry, compressed air.
