So the other day i took my skeletons down from the drying area and gently laid them on some cardboard. When i went to go pick them up i notice a lot of scuffs and scratches where the stain had been what looked to be scraped off. They were completely dry to the touch and had been drying for almost 2 weeks. Is there something i can coat them with that will keep this from happening in the future? If so what is it and if i apply it will my buckies still be flexible?
