In other words, a thicker layer of epoxy will cure sooner than a thin layer. This also extends the open time. Temperature - Heat can be applied or removed from the epoxy to shorten or extend open and cure times. After the epoxy is applied, a fan can be used to draw heat from the lay-up or application and extend the epoxy's open time. Use the back of a spoon drawn through the extended epoxy to shape a flawless fillet.
Larger spoons create large diameter fillets.
