Thanks guys.I put 2 layers of polyurethane on them for the shine. (I also spray this on my decoys for shine)It seems like the lighter spurs come from the sandhill areas or pine flats I hunt and the darker ones usually come from the swamps I hunt..not sure if that has anything to do with color but it seems that way. Maybe this website can help out.This is how I done mine. http://www.wildturkeyzone.com/articles/spur.htm
