Like everything else, the price of Aquabuff has gone up, to about $85 per 2 gallon bucket. If I went through a friend of mine at one of the Brewers yards, I could get it for $60 or $65 per bucket. One problem with it lasting so long, being water based, it would get moldy over the winter, so I would repack it in one quart cans and cover any unused portion with saran wrap, and usually give a lot of it away before it went bad. You are right about it being difficult to apply, always moving the bucket around. I am going to try the Presto products, do you know where I can buy them?
