I use lacquer thinner to clean brushes. First I use a paper towel to remove as much of the epoxy as I can by squeezing it out of the brush and into the paper towel, then I use about a half inch of lacquer thinner in the bottom of a baby food jar to thoroughly swish the brush around and remove more epoxy, then I dry it off with another clean paper towel. That method will get you several uses for a brush. Cap the thinner and use it the next time.
Dacron is supposed to be the suitable substitute for peel ply, but the word is to remove it before the epoxy completely cures because it will be harder to remove after curing. Real peel ply (depending on who you buy it from) has a release agent on it that makes it easier to remove after curing, but even then, it's not "easy".
