yeah, found cheaper - $15/4 oz (approx 25 cL). I had to add a fair
amount of acid and about 1.5 oz of the H2O2 to get etching. Still too
expensive but the store has one gallon (3.8L) of 35% for $40. I may
just go for that but will try some more bubbling to see if I can
oxidize it that way. AP is starting to look cheaper all the time.
