My father in law gave me his first rifle to g give to my oldest boy when he was born. The gun was in pretty bad shape and I always meant to restore it. After ten years in the closet I am finally doing it. The gun had a very dark stain and was blued. I have stripped the stocks and have them sanded down and ready and just finished up stripping down the barrel and getting all the old blueing and rust off. The receiver is anodized aluminum that had been painted from the factory. I stripped the paint and buffed it out to a really nice shine and plan to have my father in laws name and DOB engraved on one side and my oldest sons on the other. I had planned on reblueing and staining the wood dark again but now that everything is stripped I really like the looks of the light wood and bare metal. So my question is, is there any finish or coating that I can use to keep the bare metal look or is my only viable option to blue it again? I have looked through all the bake on finishes in brownells and didn't see anything. I wouldn't even mind maybe a "gunmetal grey", I just want something that I can do myself and will have adequate protection for the metal.
