I do want to blue it, so I'll play around with that a little this weekend.  I have a bottle of Birchwood Perma Blue that's newly purchased.  Any tips?  From what I've seen on the web, it sounds like I should work fast.  That is, wipe down in < 30 seconds.  How much do I need to worry about surface prep -- both polishing and cleaning?  If it works like wood stain I need a very even polish, but (hopefully) it doesn't.

I've never used their Perma Blue, but I have used the Birchwood Casey Brass Black.  And as they say in the video, make sure the metal is CLEAN! I soaked the brass in acetone for 10-15 minutes, then rinsed before blacking.   If there's any oil or finger print on the metal, you can tell after blacking!  But once the process was complete, the blacking didn't rub off (at least after an initial rub down anyway).

It'll be interesting to see the process you use, so please be sure and share it with us!
