What is the difference between Design-Cast 62 and 66?
DC-62 is intended primarily for casting in a mold; it is more fluid, and has a shorter working time than DC-66. DC-66 is intended for modeling over an armature; it has a pasty to putty-like consistency, and a longer working time than DC-62. The end result qualities of DC-62 and DC-66 are the same.
