It is a baked-on enamel paint. Gun manufacturers have been using it for years on low end guns, or guns that they wanted to make lighter by using an alloy frame. The old Ithaca single shot .22's had it, as did some of the late Stevens single-shot shotguns. It won't flake (like old paint on a house) but it will chip or scratch off. My dad's Henry has a few scratches in it (no, they're not character marks, they're ugly scratches) and there hasn't been a good way to cover them up except for gloss black enamel paint. The Henry is a fair low-end gun. If you want something that will look good for generations, I'd look at a Marlin 39 or older Win. 94/22.
