I have some Oxpho blue that I want to use to blue a 1911 while I decide what frontstrap treatment I want and before I decide on a final finish (this is an in-the-white gun). I have heard of a hot water method of using oxpho blue that supposedly gives a great, even finish. I read about it on one of the gun forums but through the search features I have not been able to find it. Anyone know the technique and care to share? Thanks.
