Laurel Mountain Forge says right in the instructions that oil on the barrels is no problem...and that you can handle the barrels bare handed between brownings...I degrease them any how and wear cotton gloves when handling the barrels....in fact the instructions say to sand the barrels wipe them off to remove sanding dust and apply rusting solution...no degreasing necessary.
I am much more carefull than that in my handling....
I blued two sets of sterlingworth barrels and a model 12 winchester solid rib barrel useing the same method last year and they all turned out fine ...
