Another plus for Laurel Mountain Forge is that it is a degreaser as well. Very easy to use, just don't rub it when applying it. Instructions are available on their web site (see Tim's post). I have not been able to get a shiny finish with it, though. That may be my fault, and what I have looks good. The latest project was a Deer Creek rifle. I'll try to get some photos in the next day or so.
Some of the guys on the MLML site have used it for blueing and liked the results, but they also said it's not a nice polished finish.
