Why do you think the trigger guard came out blotchy? Maybe because it was on it's side resting on the bottom of the pan.?
I think the screws came out decent, more black than bluish.
Also do they all have a matte finish when removed from the bluing solution?
David:
Probably because the impurities in the 'stump stuff' had not yet burned off or because you hit the trigger guard with oil while it was still hot.....or an uneven temperature....you should let your stump stuff burn off for an hour or so before using it the first time.
The parts would have been more blue had the temp been constant and probably higher.....again, a large round pot covering the burner should do the trick......
You will need to play with it a bit to define your process with your specific set up, always the case......when you get the temperature set and constant the parts will come out with more shine......
also the better the prep polish, the better the
final finish .....
Cheers,
