I just put the parts in a plastic tub, add enough water to cover and poored in some Cabot. I never did work out any science to it myself, so yes, I sad some ? It's been a couple of years since I've done this so if you try it, start with something small like rods in a jar. Somewhere on the net I'm sure someones worked this out ?Did you use the Cabot product straight or dilute it? If you diluted it what was the ratio?
