Ultrasonic cleaner pinholes
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?
