houdini, slodder has a good method for gluing down figures but i have never seen that done and no offence slodder but there are better less, and more logical methods like simply gluing ti with pva ( white glue) to their shoes , knees whatever and then just press down on the figure to the base, it dries clear and sticks nice and hard and tight and also its very easy to pull up incase you change your mind.
hope this helps, but slodders methos is also very good
