Yes, the thread that Karen pulled up in an attempt to smear me was from 2008, long before a system was worked out in my first shop by my employee, Manito Lara. I now have my own system, I do not dip to etch but rather put it on with a brush, and remove it immediately. For the little amount of etching that I do, I use a 29% FeCl3 reduced to 1 part etchant to 9 parts H2O. Many thanks to Mr. Stallones for getting me over the hump and sharing his knowledge with me.
