Rust resistant stainless shot consists of 2mm balls, cross pins, & satellite shapes. Highly polished surface. Simple, reliable stainless steel media needs no storage nor maintenance and requires only occasional cleaning. Use stronger compounds safely with this corrosion-resistant shot. The heavier weight of stainless steel burnishes uniformly on any metal surface. This is used for polishing gold or silver jewellery but not recommended for jewellery with stone settings. This mixture is the perfect shape and size for jewellery work. Used wet with burnishing soap. One or two pounds is the average load for a three pound barrel.
