Dayz Posted January 10, 2008 Share Posted January 10, 2008 Guys, I got myself a sandblasting cabinet...that is a lot of fun. I bought whatever they had for abrasive, it is real sand, but I find my parts quite rough after blasting. What type of abrasive should I use for: example - Rough rust (calipers), cleaning metal (crossmember) and on aluminum (brake booster)? It would be great for you that knows which abrasive to use with the type of metal/finish you want, to describe your process. Thanks Dayz Quote Link to comment Share on other sites More sharing options...
Collectindust240Z Posted January 10, 2008 Share Posted January 10, 2008 Look on Eastwood's website. They have a general guide Quote Link to comment Share on other sites More sharing options...
2003z Posted January 10, 2008 Share Posted January 10, 2008 I use black diamond coal slag exclusively. I only blast as a powdercoat prep though. the black diamond is cheap, but it breaks down fast. I used to use aluminum oxide, which lasts longer, but its pretty expensive. Quote Link to comment Share on other sites More sharing options...
JIM73240Z Posted January 15, 2008 Share Posted January 15, 2008 i have glass beads in my cabinet. works good for rust removal. leaves a smooth finish jimbo Quote Link to comment Share on other sites More sharing options...
Shift Posted January 15, 2008 Share Posted January 15, 2008 baking soda. May take longer to blast, but leaves a better finish and to clean you just rinse in some water or a solvent. Quote Link to comment Share on other sites More sharing options...
Dayz Posted January 15, 2008 Author Share Posted January 15, 2008 Thanks guys. I find that my sand (I guess) 2040 is a bit rough on Aluminum parts, it makes them white!! I would like an abrasive that can clean aluminum such as a timing cover, oil pump, carbs...etc Thanks Dayz Quote Link to comment Share on other sites More sharing options...
Cruez Posted January 16, 2008 Share Posted January 16, 2008 Like Mike (2003z) said.. black diamond is a good, general, cheap abrasive... I use it also for my coating.. Aluminum oxide is ok, not worth the price IMO.. Glass bead is good for getting aluminum back to its nice original finish..... also good for cleaning up oversprayed plastic parts at low pressure..

blueovalz Posted January 16, 2008 Share Posted January 16, 2008 I use Black Beauty (which I think is another trade name for Black Diamond). Works well and leaves an etched finish which is smooth, even with aluminum. Quote Link to comment Share on other sites More sharing options...
