Trying to find a relatively safe and available acid for Ecoating. Tried boric acid, didn't work. Process is to add acid & PC to water, boolits on a tray with electrodes attached. Supposed to give a nice even coating. Used a battery charger, don't want to go above 24VDC for safety. Didn't work. Conductivity of the fluid is too low, I need ~ 2 amps through the fluid - boolit resistivity is ~10 ohm so it's OK. Ascetic is supposed to be slightly better but I don't have any. Don't want to use a salt ( I will try NaCl). Lots of nasty stuff will work but I don't like playing with HCL or other expensive stuff. Any ideas?
Thanks.
