I have not used the envirotex, but do use the Systems Three clear coat. Pot life is pretty good. I can get 12 plugs coated easily in one sitting. I spin mine after coating. Helps with the self leveling. The times that I have had problems with it are when I try to use it in warmer weather (starts to set up before I am done) or if I have not mixed it well enough. Any more, I'll mix a batch, get plugs lined up, mix again, add glitter, mix again, then start applying it. Mix between plugs too.
