I have got a blued rifle that had some corrosion in the reciever when I got it, udderwise its in pretty good shape. I am thinking of using some fine sandpaper and sanding that part smooth and using some cold blue. Do any of you guys got any recommendations for a cold blue product? I have tried cold bluing in the past and didn't seem to get a very deep bluing.

I've used Oxpho blue and it did a great job. I applied it 3 times and it got darker each time. I've even used it on knife blades. It seems to wear pretty good. For me it was quick easy and did a good job
