Ray:
You can use putty or a thick, gap-filling superglue. You'll find the supergluse will dry and sand a little smoother, but it can be harder to work with IMHO.
I use good old Testors putty (in several layers if needed) and good old Testors sanding films on gaps I encounter. The nice thing with figs, unlike a/c or cars, is there's a little room for error and imprefection with filling seams. they're less noticable on clothers (But I'm not sure about spandex tights.....)
