I've been kinda wanting to branch out from just doing Gundam models myself.
I'm just kinda leary about the plastic quality of kits from companies other than Bandai.
... I don't rememder this. O_o
In fact, the few times I got in trouble on the ASMB didn't involve the balloon thing at all. I never even received a warning over the balloon thing (Or if I had, they forgot to tell me).
I know you weren't talking about air.
I just also know that the implied non air substance can't be expelled with enough force or volume to actually blow up a balloon. It can only fill it. That was the source of the confusion.
