I just bought a family arabian mare. She has a bent leg and I saw on a web site that putting in boiling water will heat it enough to bend it back. When I tried this, the leg got a white film on it and it won't come off by rubbing, goo-gone, or by cooling it. When I cool it, the leg temperarily stays normal, then back to the white film. Can Someone give me any suggestions, they would be helpful. Thanx
