Damn I've read of acetone vapor bathing but not of acetone polishing interesting
Yeah, just use a natural bristle brush to liberally brush on acetone and you will get similar results to acetone vapor or using something like E3D.
The metal fill one shown was sanded down all the way to 440grit, acetone, and then Novus 3 and Novus 2 plastic polishes.
You can use the micromesh for polishing plastic, but liquid is easier for non-flat surfaces.
