It's been a very long time since I built up those figures, Ron, and whatever pictures I had have gone missing over the years since the kits were originally released. From what I recall, you are absolutely right about the molded hair - it just looks strange without a little detail. I built up the subassemblies and clamped things down to minimize the gaps, gave things a quick rub down with a coarser grade of sandpaper, and then used a hot knife to texture and detail the hair. Use low heat and a steady hand to draw small, parallel lines to build up the hair, but be careful to start from the 'skin' and move outwards from there - looks a lot more natural and it lessens the chance of accidentally damaging the face or other details. It takes a little practice, but the technique is forgiving if you use a light touch. Give the hair a light scrub with a Scotch pad to knock down high points you might leave when you pull the knife from the plastic. A brush loaded with Testors liquid cement can be used to melt any loose strands of plastic pulled up by a tool which is running too hot. Just keep that "Destroyer" album cover nearby for easy reference!
