That's pretty good ... just have to whatch for fumes and such. Am I dreaming, or are most of these guys using "plastic" (Home Depot and similar) buckets, even RubberMaid containers, to store the mixes, even those who heat the stuff to 130+F for (better reaction) times / finish ? I would of thought the glass 'beakers' would be a must, especially with the acid (even if diluted). I better go back to a chemistry class I guess.
