I recently got hold of a Ruger Standard Mk1 .22 that had be stored in leather holster in a relatives attic for 25yrs or so. One side was nearly pristine and the other had rust and minor pitting on the surface. I've taken it into the white, but some very light pitting remains on the receiver and front of trigger guard and grip. I'm wondering if it's worth the effort to try and get rid of all the pitting, or If I risk taking away too much metal. So far I've just used sandpapers and steel wools. The pits are like grains of fine pepper but to eliminate them completely won't be easy by hand. I could probably live with the pitting if I have to. I plan on using Brownell's Ox-Pho to do the entire gun and since this is a first attempt I thought I'd ask for advice. I've watched a few Youtube vids. and it seems like something I can do. I'm not expecting phenomenonal results, I'd just like to do the best job I can. Any thoughts or comments welcome.
