I was wondering if there was a site somewhere with info on making JLU customs. How to pop the figures apart, best glue to use when attaching the rubber capes, etc.. Any help, as I know there are customizers here, would be greatly appreciated.

MrBear, may I suggest going to the source of some of the best JLU/Animated customs around: http://www.pilliod.net/
Casimir's site is an amazing showcase of his abilities and if you click on the 'secrets revealed' section, you just might find some answers to the questions that you asked.
