Seems like almost everybody does it the same way. I can't add any different technique but I can tell you how to be cheap. I save the containers from the the little cheese & cracker snacks. I use the container to mix the d2t in and the plastic stick that comes with it is useful for mixing . Use the small section of the container , less area = easier mixing & less waste of epoxy.I use flux brushes, just pull out any loose bristles.
