2 basic questions here. First, I typically wrap my brush with a patch, put some solvent on it then run it thru the barrel several times. I never use the "plunger". I would assume that's ok? I find it gets all the gunk out with such a tight fit. I've always worried about the bristles scratching and wearing away the metal though. Should I be at all concerned?
Last, should I oil the inside of the barrel when finished?
