I cast some clay models in Oomoo 25. I let it cure for 75 mins per instructions then they demolded beautifully. No tacky residue at all, perfect result. I stirred up a pot of dragonskin 10 medium ans checked the date on the bottles, all good.After curing for 15 hours the dragonskin was tacky anywhere it was touching the oomoo but firm everywhere else.I am thinking it may have something to do with waiting before using the oomoo as a mold, but I've seen people doing that in their projects with no problem. Another thought was that the clay I used (Sargent art plastelina) may have left too much oil on the oomoo, but when I demolded they didn't feel oily at all.Needless to say I wasted about $50 of product. I have more coming and don't want to mess it up this time.Any insight would be appreciated. via /r/DIY https://ift.tt/2MiEqTu
