help---i have never owned any firearms--but i have some hardware -levers arms and bolts and nuts- which i would like to recoat with something to make them ''black''-once more. i thought that maybe a gun blueing kit would do this for me . i have never done this before --do not know what the process is or a ''reputable'' manufacturer to buy from. this hardware is for my bridgeport mill which iam rebuilding from inside out. do you think gun blueing is a good idea?? i really need your input and all input will be greatly appreciated. thanks in advance. re steve in montana
