I just got this posted on another list today, haven't had time to verify it, so use at your own risk, YMMV, etc, etc, and I didn't sleep at a Holiday Inn last night.

This piece below I'm fwd. from a friend.At sometime we've all needed to
re-blue small parts of whatever. And my experience with the stuff you
get at the store usually is less than satisfactory.This the below works.

 If its regular old steel (and not stainless or aluminum), you can blue
 it at home for less than $10. Go to Lowe's and buy a couple 1lb jugs of
 Stump Grinder, which is nothing more than Potassium Nitrate. Remove all
 rust and any old finish off the trigger guard, and make sure you
 degrease it. Heat the stump grinder over the stove until it completely
 melts into a liquid (which may take a little while), and simply suspend
 the trigger guard in the liquid for 10 minutes. Remove it, neutralize
 it in some good old water, and you will have a nice "old world" blued
 finish. I've done a few small parts this way, and they all came out
 very nice.
