Spray CRL Polishing Oil on your abrasive belts and discs to keep them soft and free cutting. CRL920 helps to reduce "loading" while it improves finish edges on metal and glass. Spray directly on belts, discs or abrasive wheel before starting, then re-apply lightly as needed. Gives you longer belt life and a brighter, faster polish. Net weight is 11 oz. (312 g). 12 per case.
