My wife put a couple of small scratches on her .30-30 barrel while getting out of a tripod stand this weekend. I broke out the Birchwood & Casey Super Blue and you can now only see the spots if you're looking hard for them in good light.
"Great", I thought, "I'll just touch up that small scratch I put on the .45-70's receiver when I was trying to punch those friggin' pins out"... Not so good on the receiver. Used the same steps right on the bottle that I'd used on that barrel, and now I have a shiny blue spot about half the size of a dime, where before I had just a small scratch. So, after the end of the season on Jan 31, I'm sending it in to NEF and paying them the 30 bucks.
So obviously, the Super Blue doesn't do as well on the more polished receiver, but appears to have done a great job on the barrel.
I also have the B&C Pen, the paste blue, and some other (Outers, I think), but didn't even reach for them as I don't like the results I've gotten from them.
Cold bluing is not all that great to begin with, but since I own 4 NEFs now I probably will need to touch up a spot on a receiver now and then. What's best?
Thanks,
Rick
