Milliput® is a two-part epoxy putty. Milliput is used by blending equal amounts of each stick (two in a pack), by rolling and kneading until the colour is uniform and free from streaks. It can then be manipulated like modelling clay. Milliput goes rock hard in two to three hours at normal room temperature (faster with heat, and can be kept as putty for 72 hours in the freezer).
