It was indeed a curing issue. I cured these until the green shade was completely gone, and used Plasticast (heavy mix) with an 8hr burnout and they came out very well. Little to no porosity.

With the FTX Green, the cured piece was strong enough where I could file all of the grow lines off before casting. The FTX Cast is much more brittle so I'm apprehensive to start filing on it. That's why the surface is a little rough on these.
