Anyone have any luck using a random orbital sander to etch glass?

Nope. Terribly sensitive to the relative flatness of the glass and the
sander. Results are usually ugly. Silicon carbide paper is needed.

Best technique is to use an air-powered grit blaster. Dead easy to
use, easy to get good even results, even on curves. Masks well with
self-adhesive plastic films too. if you don't have blasting kit, try a
glazier.

I won't handle etching creams as hydrofluoric acid is just far too
dangerous to work with.
