I used 1200 degree Duplicolor with Ceramic engine paint, baked it about 3 hours afterward in the oven at whatever they recommend on the can.
The unpainted part of the barrel and the barrel extension both turned blue, but the unpaintd part of the gas tube remained silver.
Now, years and several thousand rounds later there is no trace of any loss of color, adhesion, or anything.
And I'm not sure about the SS turning blue, but if anything this has been one of the most outstanding barrels I have ever had. Very accurate with 55 through 77gr ammo.
