Just went thru the search and I know this is not a new thing but I pulled out my mold to cast some feet. I used polycast and after half hour went to pull. Material detail was fine but the legs were soft. I could still bend them. Even after a couple of hours they were still that way. I will probably go back to 3080 with some dye. Can anyone tell me what or why the polycast is not setting up.... It is not even 6months old...???
