One-time is just what I had in mind.

Appreciate the flag.

People might be reluctanct because of the tin in the bronze. I'm not
sure what it will do, but I'd avoid putting anything other than copper
in my etching tank.

You can always try with a one-time use small batch of etchant first.
HCl and H2O2 (3% dilute) will do the trick.
