OK, I tried again last night, and kind of got an etch. Not very deep at all. I think I have to increase either the salt in the solution, or the power it's getting, or both. Any ideas?

I had scrubbed the heck out of that piece before I tried. Today, I bought a roll of aluminum flashing from Lowe's and cut a piece of that. I sanded it, then scrubbed it with Dawn to get rid of any oils. I'm now applying the resist (P&P Blue), and I'm going to give it another try tonight. I'll let you know how it turns out.Thanks so much for your reply and help!Connie Carufel

Want to let you know that I did actually get a much better etch than I thought before I cleaned off the resist. It took two hours, but the voltage was low, and the salt solution had been used before. I mixed up a new batch of salt water today, much more saturated, and got a new charger. I'm going to try it tomorrow with higher voltage. I want to clad small gift boxes for the children for Xmas. I always bite off more than I can chew. Maybe only my two grandkids will get them this year. Anyway, the flashing I bought from Lowes is thin and cheap, so I can experiment. The only expensive part is the p&p blue. They are worth it, though!Want to say thanks!I
