I can't speak for everyone, but mine all appear to be fine. Allow me to be transparent, long-winded details inside spoiler tag: Spoiler: Details * I live in a hot, dry climate, and the figures are kept indoors in minimal sunlight with the A\C typically set to 75. * No exposure to smoke, incense, candles, compressed air, or any sprays such as air freshener or Lysol. * I attached a few different blast effects of different colors onto a few different Battle Masters of different colors. * After about 3 months, I was able to easily remove all of the blast effects from all of the Battle Masters and there was no evidence of transference of paint, color, or plastic, or of any chemical bonding taking place between the two pieces. * The color of the blast effect and of the Battle Master did not seem to matter at all. * The weapon ports of the battle masters did not look scarred, pitted, damaged, or like they had lost their basic plastic luster or suffered any kind of physical damage or deformity. * In contrast, every time I have put blast effects onto painted plastic, it has caused paint damage and transference within a few days. And because I don't like to double post, here is the latest update to my Kingdom Cavern Brawl! Spoiler: More long-winded details - Core Soundwave has decided to help in the booth as the microphone operator and co-host, while also managing the Lazerbeak Camera Corps. - The sides have been mixed up, and make no sense. Maccadam: "Oh, come on. Let's be honest, here! They never made any sense to begin with." - There is always something creepy taking place to make Asuka recoil in horror. - PotP Inferno joins the brawl because he was lonely in my closet. - Still really tricky to balance the daylight across the two sides, since my window faces a weird direction. - The Cheetors are back out of jail and Bonecrusher has been moved to the penalty box for stealing the last round. Dino: "Cheetor! Stop making fun of my wings!" Cheetor: "What!!? I'm not! I just like to put my cheetah legs like this, honest!"
