1 gallon for $50.. that's like not quite 4 liters, right?
I dunno exactly what i pay, but with 1 liter bottle it's _well_ below
10eur, i expect maybe 3 or 4eur, if that.
It's not food grade, but $50 seems quite excessive to make PCBs with.
Also, this seems to me a bit like a snake oil vendor, and i would refrain
from buying anything from such sources on principle.
