Acetone has less predictable, less controllable and uneven (caused by gravity and how acetone vapor moves in your chambler) final result and a glossy finish you might not want which could be achieved by other means such as spray painting.

I'd give sandblasting a try. I'm clear on what cabinet I should get. But what's the most minimal compressor I can use? Low on budget.

Maybe I'll try a rock thumbler first. Still less predictable and controllable, but somewhat more even and not glossy.
