DesertDug,

Glad to see you solved your blueing problem.

As for bedding scope rails, I personally have never experienced the need to do that.
I've had to torque the screws holding the rails and use Loc-tite on the screws to keep the screws from backing out under recoil but I have never had the need to bed the rails themselves.
I guess if the action surface or the rails themselves are not smooth enough, it might be a solution.
Personally, I would smooth the mating surfaces and then mount the rails. Now that you have the 'Super Blue', you should be able to cover any smoothing marks.
You're the only one who can tell if the rail mount will really need to be bedded.
