I put the second coat on the next day. I also don't use a spinner. I hang them and let them drip. the next day I hand the 180 degrees and let them drip again. If it's a popper, sometimes you'll be left with an epoxy-cicle if you don't stick around and wipe it off with an acid brush. E-tex is pretty easy to use, just don't touch the plug with unwashed hands, human oils, potato chip grease, and anything else will cause voids and "fish-eyes". Wash your hands religiously and watch what you spray in the shop and you'll get glass-like finishes.
