I am refinishing my enclosed boat trailer and attempting to bring it back to near new condition. I have already added new tires and wheel bearings and repainted the wheels, now all of the wood gets refinished. I have a small panel that I want to epoxy before it gets painted. When I got out the epoxy the hardener was fine but the resin had solidified. Not wanting to spend over $100 for a new batch when I only need about a cup, I brought the resin in the house and put it in the sous vide for 2 hours at about 115 degrees. Bingo! It quickly returned to liquid form saving not only money but the time it would take to ship here.
