How are you all doing? This is more of a curiosity question so I did not want to post it in the troubleshooting section. If I should have I apologize. I live in Michigan so with cold winters and airbrushing in my basement I use a warm water bath for my paints to warm them up before I shoot them. When I do this with Createx opaque black it forms bubbles in the bottle and there is pressure inside also (when I opened the bottle a paint bubble popped and got all over my project.) I do not have this problem with any other opaque color by createx and also do not have the problem when I use Createx wicked colors opaque black (I have done this with detail and jet black). My question is, have any of you done/experienced this? Also could it be that it is an older bottle of paint that does not get used much, so maybe a chemical breakdown of some sort? I am just curious because it is only one bottle of paint that does this.
