I used some liquid GS to fill some small gaps where a figure's arms meet its shoulders. Being LGS I had to apply 2-3 layers. I used a knife to remove excess as I applied, but there is still some leftover dried GS outside the gap, and I am afraid that it will make for a coarse surface. It's in a hard to reach area due to the model's pose, so filing may be next to impossible. Anyone have any tips for removing the excess lumps or smoothing them out? Thanks.
