Caswell zinc setup, solids in mixture
I’ve been using the Caswell zinc plating and there’s quite a lot of undissolved solids in the bath. Is this good? Is it normal? Should I strain it out? It doesn’t dissolve when I heat it up or mix it around. I also have difficulty getting things coated with zinc or getting the finish I want even though I’m pretty sure my amperage is set properly (about .1A per square inch). Sometimes I can sometimes I can’t. Is that the culprit ?
