Homebrew PCBs

I used some of that etchant and its storage life was not good. Mix just what you need by figureing out board size, per
specs that come with that bag only and it will work, and work ok but storage life was not all right there for a lot of money wasted I think. I later on bought a 1 lb. container of  Ferric chloride, anhydrous 99.8% and its storage life is better and I beleive a better deal. I also found it on E-Bay.
