I have been using this epoxy for years now with little to no problems. All of a sudden the epoxy is separating on the plug while spinning and dries with brae spots and pooling. I have been using several different airbrush paint. Tried using another box of E-tex but didn't change anything. Seems to be mostly on the white paint so I will be going back to Createx. They dried nice and hard only with the epoxy all over the place. Has anyone experienced this before? thanks
