Grease like substance on optimus?
So I noticed this 2 years ago when I got this figure, but once I take the arms off there's this weird substance that looks like grease. Should I be concerned? And js there a way to stop this

My custom bumblebee for my universe. I plan to put this head on the SS TFOne bee when I get that
I'm planning to make a custom Tarn when I get that AOTP Unicron, but don't know if the ball joints match. Anyone tested?
This is my definitive megatron until I get the IDW siege megs upgrade, BBM megs or the upcoming TLK ss megs
After almost a year I have finally found the right head for my custom - the killing arm upgrade kit head. I gave him a bayverse inspired paint job and put these arm blasters on him inspired by armada prime. I can't believe he's finally completed. Thank you all who gave me tips over his creation process
