This is my little brothers bull from a few years ago. He was a bonehead and let them get chewed on by a dog and left out in the weather. He is away at school right now, and I was hoping to try and fix them up and mount them on a plaque for him for christmas. I have some Aves Apoxie Sculpt I was planning on using to fix were the dog chewed them up. I also have some Potassium Permanganate for staining the antlers. I am assuming I am going need to get some of the pink and green cleaned up and or bleached? I was hoping for a little insight into weather I need to do that before I stain with the KMNO4 and if so, how I should go about doing it. Thanks in advance for any suggestions.
