Good to hear a positive outcome. A couple of things I find useful are a copper hammer and a very light swing using it. I try to use my wrist not my arm like when driving a nail. Light hammer blows leaves little or no marks on the exterior. Another thing that really helps is Polyethylene Film Tape sold by Lanmar. Really keeps the metal clean and very helpful when fitting new screws to a gun as well. I use the .003" most often but the .010" is handy as well.
