Steel grit also works very well, but if you don't do some "protecting" of the inner cabinet, it will eat through the cabinet also. Rust removal is no issue for steel grit - comes in various grades also, and honestly in my experience lasts far longer than anything else.

Yeah

I use a stainless steel Sheild behind what I am blasting.
if I use Steel shot.

With your Idea I may cut some sheets at work to protect my cabinet.

So there is a difference between grit, and shot - you are probably aware. Shot is like small bb's, grit is just that, sharp and angular. They both leave very differing surface prep's once blasted.
We use thick mud flap style rubber material to line the inside of our cabinet at work, usually 3/8".
