I have done them on aluminum in the past, you just have to make sure they are clean. As for width, you need to multiply your exact shaft diameter by 3.1416 to get the circumference, and round up! Yes, you will get a little overlap, but that is fine. As for the length, that depends on your overall arrow length, and the vanes you wish to use. They offer this option called double dog. It is a clear wrap the goes on over the decorative to keep it from getting scuffed up. Also, you can get reflective, which I did on the Zombie's. Like Anthony said, contact them, they make it real easy, and answer the dumbest questions!

Don't ask me how I know that one!
