Hello, I'm new to working with bones, but I've done A LOT of reading and research so I know a good bit now about how working with bones goes. I've only been doing it about a month and currently have some stubborn deer bones degreasing in acetone. They went through many, many baths of hot water/dawn soaks for three weeks, and were still bleeding grease so today I made the jump to acetone. When the bones are done being degreased (when ever that will be but hopefully in the next 2 weeks or so) I have a special project I'm going to use them for. I'm going to make them into windchimes and will be selling them. The windchimes are going to be something that sits outside for years. So I need to seal the bones with something that will make them waterproof for many years. After a few years I don't want them to be falling apart or become discolored due to the elements. I don't have enough money to buy Polaroid B72 so what would be a different and cheaper option that will work just as well? Also, I'm looking for a waterproof seal that won't leave a super glossy looking finish. I want the bones texture to appear as natural as possible. Any advice and information would be greatly appreciated!
