I've finally got a Motormaster tat I picked up from an ebay seller and all the limbs I need to make him........ but the legs are so floppy he keeps doing the splits. As a makeshift, I've got a rubber band around his legs to try and hold them together. Worse still, he's really top heavy and unless his arms are pointing down he'll flop forward.

I have a photo of it, if that helps convey the problem.

Am I better off just replacing Motormaster with another one, or is there an easy way to make the waist tighter. I'd heard some people use clear nail polish to make TF joints tighter, but never done it before.
