I have purchased your 100lb pressure blaster with the soda blaster conversion kit. It works great as a soda blaster (though a bit slower than I would have liked). Now I would like to use it to remove some rust and have purchased some aluminum oxide for that.
My question is, do I have to remove the soda conversion kit to blast with the aluminum oxide? What if I combine the soda and aluminum oxide (80% soda/20% aluminum oxide)? Are the air volume and pressure settings for aluminum oxide the same as for soda?
