I'm just a beginner, but I've read you can get MA at the hardware store.
Home Depot it closest to me, though I see a lot of mention of Crown from Lowes.
This from Home Depot (if it works) is 2 gallons for under $11. A better deal than lowes and it seems to be 20 Baume (31.45%)

Anyone see any problems using this?
