I have a 2 1/2 k frame revolver i would like to re-finish. I have been told home re-blueing is difficult. The gun has some engraving that i dont want to lose. Any ideas on a finish i can do at home that's easy and good looking. I wont be carrying this gun. It will probably remain in the safe til i want to play with the snubbies again. Any experience out there with the spray on / bake on finishes?
