Small particles with sharp edges at high velocity? I don't see the difference between it and sand and walnut chips. Nowhere near my wiring harness. Hard surfaces perhaps can be "managed" by distance. The video I looked up showed a very rusty bolt being cleaned down to shiny metal. I'd not be inclined to try to use it on paint unless I wanted to strip it.

(I'd considered getting one to blast the calcium buildup off the pool. The CO2 leaves no residue like glass beads and as it evaporates reacts with water to form carbonic acid which lowers pH. Machine is medium price but the dry ice is hard to find.)
