Yeah, I tried that method, but I just want to put a board in a tank and walk away to do something else while bubbles do all the work. Plus, all of my surplus-purchased PC board material is double sided, so using that method I have to flip the board over to etch off one entire side since I typically try to make single sided boards if at all possible.
