MASTERPIECE 17 , 18 & 19 ISSUE.

Was kinda cleaning up my masterpiece collection and realised that the joint/screw? On the elbow Are like corroding or something..... same goes for my smokescreen & prowl it's a minor nitpick but if there's a way to solve it it would be much appreciated. I was surprised considering I take really good care of my transformers and usually after I buy em, they go straight to the display case... are any of you guys facing the same issue? Furthermore, for some reason my streak won't hold his gun on his right hand would appreciate a quick reply.... thanks!
