I have a friend who restores historic military equipment. Tom had a contract to repaint tracked vehicle gate guards at at a US Army base. The paint contained something intended for reflecting the radiation of a nuclear blast. That, along with other alarming chemicals, required building a sealed enclosure around the tanks. The crew removing the paint wore full hazmat suits & the highly toxic dust was carefully gathered & removed. Needless to say, apart from the color, the new paint was nothing like the witches brew originally applied.
