After hearing a lot about this Aves Apoxie stuff, I decided to give it a try. It was a terrible experience. It stuck to everything and wouldn't hold its shape, even when nearing the one hour mark on its 2-3 hour time span. I followed all of the directions, but I just couldn't get the stuff to work at all. Has anyone that used this stuff had this kind of trouble? I got Apoxie Sculpt, but since I haven't tried the other varieties yet I'm not sure what to go by in terms of how firm/soft it should be. Is there any way I can make what I have more firm? Any advice would be greatly appreciated, thanks!
