I'm in the process of touching up a few g1s right now, I'm trying to decide the best way to approach tightening things up for some of their parts. I guess I'm talking mainly of sliding pieces that 'tighten' into place (by one small piece of plastic being wedged between two increasingly narrowing ones, etc.), such as for say Sandstorm and Astrotrain's legs, as well as pivoting hinges that get so loose they're floppy and lose the fight against gravity, such as say Astrotrain's wing tips. Best methods? I've heard of nail polish before on this site, would that leave a smell though?
