2 ounce Mould Prep Bottle. I cannot say enough about the importance of using a product like this on your bullet moulds. I nearly ruined a Paul Jones custom bullet mould because I did not use this product, never again!
Apply to the top of the mould, the bottom of the sprue plate and to the alignment pin holes to prevent galling. This long wearing dry film micro graphite lubricant can be used on all aluminum, brass, iron and steel moulds. 2 oz. bottle goes a long way.
