Jeb, the worst thing about over cleaning is the usage of a metal rod and it hitting the crown - or that you drop it or you rub it too much - Its like shooting, anything can happen - when I was younger I cleaned much more, but now I am 'old', I don't love cleaning as much
Its like many things, if it makes you happy, I am all for it
An interesting observation, many times I hear about it being factory fresh, or been in storage for many years (like since WW2), but when I went to europe for three years (turned out to be 7), that I had cleaned my guns left at my dads, then coated with RIG grease, by the time I cleaned them, you'd have sworn they had not been touched since WW2! Looked just like old cosmoline
