I use BSI 30 Minute Slow Cure Epoxy... I never measure but do a 5 count of each part into a plastic medicinal cup. Mix the crap out of it with a drill and piece of spinnerbait wire bent at 90 degrees. Then I dip the brush in DA and any bubbles will disperse. That is more than enough for 2 baits which is all i have time to do if I take my time. I will do the lipless as my 2nd of the two baits if possible. As the DA evaporates and the epoxy THICKENS, it does not "pull" away from the edges. I find the key to brushing epoxy on is to have enough on the brush, so it will "flow" as you brush it as opposed to the epoxy being "pulled" with the brush. A little more info here than needed to answer the question, but this is my process and works very well for me.
