Homebrew PCBs

Stefan,

Yes, there is. Finally after half a dozen different places  that only sell 10% HCl, or muriatic acid "replacement", today I finally
found a bona fide single purpose pool supply establishment that still carried 2 gallon packs of 32% (Muriatic Acid) HCl for $11,
same price as the 10% stuff. Several Chemical supply outlets I tried would not sell hazmat to individuals, or wanted $25 or more for
hazmat shipping charges on top of up to $138 for 37% stuff. I'm going to try the 32% HCl. 

Thanks everyone for the help,

Roger

I'm absolutely positive there's HCl to be bought in California
somewhere. It's just a matter of finding the source.
