Looking great so far, my friend @dbutlr! Regarding the Future mishap, to my knowledge, Future, once hardened, is very difficult to remove and any strong agent used will have a bad effect to the camo and, possibly, to the plastic underneath. Normally you should lightly sand the area to even the bumps, but almost definitely this will remove a good portion of the camo paint, meaning you will have to locally repaint and re-Future...
Before doing so, how about applying Future locally with a brush: it might even the bumps to an acceptable point (but be careful for it not to stagnate at places, as it will create even more "lumps"). If it works, it works, otherwise you might proceed to sanding and repainting.
