I picked up a 2nd hand wool mix winter coat yesterday from a charity shop. It looks unworn but a quick Google suggests it's what they call vintage, i.e. a few decades old.
Anyway, it has a fairly fine metal zip that's a little stiff and as it's such a nice coat I'd like it to last. I think the zip could do with something to make it smoother to use but not sure what's best. I have the usual stuff about the place; various waxes, silicone oil, silicone grease, graphite, gun oils etc but is one thing better than the other or is there anything I should avoid?
