Jack,
I have played with OxphoBlue and been able to get quite a shine. I start by cleaning the surface with alcohol. Then I warm the area to be blued with a heat gun. I then apply liquid OB to 4/0 steel wool and apply it to the area along with more heat. The OB will dry and look terrible. You can either keep polishing with the steel wool or apply some OB to a patch and polish the film off. I keep polishing the area until the patch is almost dry and there appears to be no OB remaining on the barrel. You can repeat the above until you get the desired finish. When satisfied, finish by polishing with a patch slightly dampened with OB. Keep rubbing the surface to bring up the shine. I then coat with Ballistol which deepens and enhances the color. As you probably know, OB is pretty user friendly. The heat, steel wool and buffing seem to be the real keys.
Good luck and have fun.
