I use a garnet abrasive that is made for water jet machines. 80HPA made by Barton. Works well, or another is coal slag type like Black Beauty. In general, recalling earlier comments above, you want med to fine media (smaller hammers) and lower air pressure (lighter hits of the hammers) while holding the nozzle at an angle (less impact). When blasting inner doors, inner structures for hoods, trunk lids, etc, block off openings that you don't hit open areas and get the issues I showed above.


I wouldn't recommend soda, it will change PH of the metal where Epoxy doesn't have it's bite anymore, and may pull off in sheets, or sand as most also contain caustic salts, not something you want impaled into your sheet metal.
