BoostedRex Posted February 18, 2009 Report Share Posted February 18, 2009 Do you guys media blast the inside of the cases? If so, has anyone had any problems with the bearing journals(clearances, scratches) and sealing the cases back up? I'm taking my powder coater my cases tonight and he wanted to know how good he has to tape them off. Quote Link to comment Share on other sites More sharing options...
boneyardbanshee. Posted February 18, 2009 Report Share Posted February 18, 2009 (edited) I personally woulnt blast the insides. I dont know how the other guys would go about it. But a degreasing and a good outgassing should prep them just fine for the inside. Lightly blast the outside to remove casting marks/bumps. But yeah, a good outgas before the powder should prep them well. It will burn off any oil and residue and also raise rap from in the metal. All cast parts should be outgassed to prevent bubbles in the finish. Edited February 18, 2009 by boneyardbanshee. Quote Link to comment Share on other sites More sharing options...
