Well maybe, I have compressors at two of my places and never use them for gun cleaning. I don't believe that blowing out a barrel with air will get the water out of the pores 100% I live in a very humid area and need to be sure the barrel is completely dry before I oil it. I use hot soap and water to clean corrosive powder residue and the use boiling water for a rinse the heat drys the barrel in a couple of minutes and it also opens the pores in the metal so that when I oil it the oil will go into the pores and stay put. I also believe that needs will change according to the area you live in and will sometimes be quite different in different areas, so people should not be surprised when they have to do a bit of trial and error to find out what is best for them I had to do some things different when I moved from northern IL to down wind of Greers Fairy Lake in AR. Was expensive learning to. Lee
