Okay, so, after I got Classics Hound, I discovered one major flaw - His head is EXTREMELY loose. To the point where, in order to keep it from wobbling, you have to make him look to the side, which makes certain poses hard to do. Secondly is my G1 Soundwave, who has the same looseness problem, except it's... everything. Legs tend to be weak and make him fall over, he can't keep his arms held up, and his head falls down far too easily. How do I fix these loose joints? I know there is a fix some people use, but I can never remember what it was... Nail polish or something? Please let me know.
