All of the blues work vary well. If you have been resurrecting it have found that every one starts off with it must be clean. However, none of them will say how to clean it and that is the secret to the blue working well. It took me about 5 years to find that secret. After trying everything you would think of for removing the oil from the gun I said to my self - what have I not tried?I'm looking for some recommendations for the best product to use to re blue a rifle. I have read a lot of reviews on a couple of different products, but I can not make my mind up as to which to use. Any suggestions would be greatly appreciated.
