Best Gun Black

[Brien]

Hi Folks,

I am building a Frankenavy Luger (Barrel replacement will be courtesy of G.T.)

Since most of the parts are mismatched and hence different finishes, what is the absolute best Gun Black product I can use. (I'm going to attempt to refinish it myself....maybe (can't really screw up a buildup....at least I don't I think I can)

Regardless, since I really like a black finish as opposed to a blue, what is the consensus on the best product to accomplish this? Ease of use can also play into answers as well. Would like to have a happy medium on both ease and end product, but if it takes effort so be it.

Thanks for your time in reviewing this post and or course for any answers.
