A friend has gifted me a little 100W ultrasonic cleaner (typical Chinese) that he was using to clean brass for reloads.

The cleaning solution (salt, vinegar, dish soap, water) seems to have created pinholes, probably where there were inclusions near the deepest drawn section.

Could this be painted with epoxy paint? Or should I try to TIG a thin SS sheet over the bottom tacking it at a few spots to keep it moving?

Stainless steel will corrode in stale salt water. If the water has oxygen in it, no problem

I would coat with epoxy and start looking for a SS container to replace the original.. and store the cleaning solution in a separate container when not using the cleaner.
