I'm working on my very first kitbash using a spare Armada Blurr. I was wondering if anyone had any advice on adding in new ball joints - I've had a look around and it seems that people use bionicle joints. Are these a cheap and effective way to do it? I'm also attempting to mould a new piece, does anyone know of some kind of putty thing that can be moulded and then perhaps heated to 'set' and remain rigid and solid? I've been trying to take the guy apart so I can clean and then paint him, but some of those screws just will not move. Those things are *tight* - any hints for getting them out other than just pushing and twisting the screwdriver as hard as possible while swearing at the toy? Thanks guys!
