>>7037915For joints that are to tight or severely stuck with paint I use pic related. Shock oil is made to use with plastic parts and you can dip the tip of a toothpick in it and touch it to the joint that's stuck then carefully work it loose. Seriously use a TINY amount, it goes a very long way. And make sure you get the heaviest weight oil you can so it doesn't run everywhere and make a mess.
