I have been looking around at various products for rust removal on some mags I have, and one that I have run across is the "rust conversion" paint. There actually appear to be two types, one that is a polymer coating that competely encases any slight rust so no oxygen that can reach it, and one that seems to use a chemical process to blacken the rust (thogh it warns it can actually rust clean metal).
So has anyone used any of these products to reapint or undercoat a mag? I have both some Yugo mags and some of the CFS "special deal" mags that have surface rust and some deeper pitted spot rust. I have loosened up and removed any loose rust, but don't want to wire brush every last little spot of rust because honestly it will take weeks to do all 32 mags, and I just don't have that kind of time.
If no one has tried it, I might say "what the hell" and give it a try on a couple of the real beater CFS mags I have once it warms up outside.
