I received a tinned 45-70 cartridge in a box among some others that had something that resembled varnished over the bullet and most of the case. It was not an intentional “painted-on” coat but looked like it had been spilled on it. It was old enough to be fairly removed with a piece of copper Chore-Boy pad but the removal process shined up (and scarred a little) the 500 gr. lead bullet that was coated very thickly with the stuff.
I know that the lead will never have the original patina but does anyone have a method of dulling or artificially aging the lead back to near the older appearance? I know some of you collectors have some tricks up your sleeves like carry it around in your pocket but I don’t know if that particular trick will work in this instance??
