I am installing some new sights on a pistol and in removing my old rear sight with a brass punch, I missed once or twice and left some brass marks on the slide. Is there an easy way to remove these gold streaks from the stainless slide?
I have found that it is near impossible to not make a mark when using a brass punch on sights. To remove the mark, use a little bit of oil and 0000steel wool. Or use a plastic punch instead!
