High quality mil spec GLASS BEAD #3 – Made in the U.S.A. 5.5 on Mohs hardness scale. Quality GLASS BEAD is an excellent media to provide smooth, bright, contamination-free finishes. These hard round particles close up surface roughness and porosity by peening. This helps prevent corrosion, resist rust, staining and fingerprints, and provides a bright, tight new surface. Peening of most any surface (other than light sheet metal) can help its appearance and longevity, whether it is to be painted, plated, powder-coated, or left bare. . Peening helps to combat stress-risers that can produce cracks and increase fatigue resistance to critical parts, retarding fatigue and fatigue corrosion.
