I've read a lot of recommendations for Brownell's Oxpho Blue, so I ordered some of the creme last week to blue a frame that I bought recently, the one someone welded on, so it needed to be completely reblued, not just touched up, followed the directions with one exception, I heated the frame as recommended by gunnut69 in the Gunsmithing forum. It came out very good, at least as good as some of the worst blued frames that come from H&R.
