OK I use Clear Castin' Craft resin for my clear casts and I came across a problem....There was a hole in the can and the resin didn't harden 100% but it turned from a Liquid to a jelly type substance. Is there anything I can use to turn the jelly back into liquid form? Because I am going to use the rest of this up and buy some new resin and I hate to waste this because it is still usable. Oh and I already tried using acetone to thin it out it worked but once I put the hardener in it never became hard. Please LMK Thanks!
