Mini update today.
I spent an hour and a half base coating the hills and modular river sections last night. Woke up this morning to find little white spots of poly-filler still showing through, grrr.
More excitingly here is a pic of General Sutov's Gunpit and Trench creations. The General has been cranking these out for Saturdays game along with the other required field works (which IIRC I was supposed to be doing). Great work buddy.
