Only One Batch Left...
After carving up the scenery to accommodate the finished trestle, there was a fair amount of cosmetic restoration to do, although it's quite difficult to discern in the image below—the flaws often blend naturally into the surroundings when rendered in two dimensions.
In order to get repair material into all of the recesses without adding any significant thickness, I mixed up a small, very soupy batch of Sculptamold, and brushed it onto the scenery with a half-inch stiff-bristle paintbrush. I had enough left that I was able to fill in the terrain around the wharf as well. Then I continued on from there and blended everything together with a top coat of the thin mixture, which did a nice job of eliminating the patchwork-quilt effect of having built up the terrain from multiple batches of Sculptmaold—even though groundcover materials would have done the same thing.
While it's still wet, this batch of Sculptmold photographs as an odd shade of bright olive green, although it dries to a nice netural grey. This also puts the trestle installation on hold until it's all dry. Then, with the trestle in place, I'll need to mix up one last little batch of Sculptamold to fill in around the bridge footings, and that will wrap up all of the terrain. I'm psyched!
