The problem with metal is, even if leave small pits of rust, it will show up later. I think sand blasting at this point would be over kill unless it's a friends & you can do it free. I sanded the block smooth before the machining then, used 3M's rotery sanding disks to clean it up. I actualy had to wait for 3 weeks to paint it, too busy so, I sprayed it down with W-40. Cleaned it with prep-sol the painted. The epoxy primmer is really good stuff & will not let small amounts of pitted, rust to come thru. I've used it for several years now & havent had a rust come back. Just get 99.9 percent of all rust perfectly, cleaned off with your tired, bleeding & sore little fingers ..................JUST KIDDING !
