So a buddy is giving me an old winchester lever action 30/30. It has some rust. not pitting, but not surface rub off either. It looks like it used to be a stainless type finish, ie: bare metal. so... i'm wanting to refinish it of course. my question is this. do i want to go with like a 600 grit sand paper to knock the rust off and then a 2000+ grit like you would in a polish job... then refinish it or what? don't have access to a bead/glass/sand/media blaster....
