Part 2 - Reviews of Epoxy 2 part thread finishes
by Chris Ward, Craftsman
All 7 epoxy 2part finishes listed below have been tested in an unheated workshop on an average September/October day. The samples were turned continuously using a Seymo Rod turner/Fly dryer. On average they took 10 to 12 hrs to reach a hard surface, 24hrs later I was comfortable all had fully dried and most had fully cured.
