I'm enjoying following your progress, Steve. 
While I will use them when there's no other option, I'm not personally a big fan of putty fillers, and find it's faster and gives a good finish more easily when I use styrene strip or rod to fill holes in plastic. Simply choose strip or rod slightly larger than the opening (.003"-.005") then liberally coat hole and filler with solvent-type cement, and jam the filler into the hole. Let it sit until hardened, then trim off the excess with a knife, and finish with files and/or sandpaper. In most cases, no further filling will be needed, and the plug will be imperceptible once painted.
If the hole isn't compatible with the filler stock which you have on hand, use a drill, file, or knife to enlarge the opening to a size appropriately smaller than your filler material.
