I recently bought a lot of the new Citadel/ Gamesworkshop paints off of ebay. These are the newer versions of paints they released a couple years ago. Half of the paints I received were solidified and extremely gummy. I don't understand why because they were brand new paints, I actually had to break the seal to open them. I have paints several years old and they are still good. I tried thinning them out with paint thinner but it still seems really thick. Does anyone have any experience with this happening to their paints. Should I just chuck them or is there any way to salvage them. Thanks in advance for any tips or advice.
