Before mixing your epoxy finishes, fil a small container with hot tap water. Let bottles of epoxy stand in water for 10 minutes. This helps to get the viscosity’s nearly the same consistency.

 Before drawing the finish into the syringe - insert syringe, pull plunger, pick up small amount of epoxy, lift. Eject small amount back into the bottle. Reinsert & fill to amount needed. This gets rid of the little bit of air in the syringe.

Mix epoxy thoroughly then pour out onto aluminum foil. This will give you a slightly longer working time.
