Anybody have any experience with gluing playmobile?  My girls quickly trash the assembled parts and I'm tired of both picking up the random pieces and doing constant reassembly (they DO like the "sets" assembled - it's not that they prefer a pile of pieces).  I tried using a glue-gun (low heat glue, not high heat), but that didn't last very well.  I have superglued a few items that really just needed to stay together, but I'd prefer to use something more economical and less potent.  Ideas?
