Cleaned and greased. Not going to paint as it will always have something oily in or round it! The jaw screws were mostly stripped and the jaws slightly banana-shaped. The jaw beds flat though and minimal wear elsewhere. So I've helicoiled the threads, turned down some M8 countersunk screws to fit and ground the backs of the jaws flat. Bit of grinding on the front, but the jaws come together properly now and don't move.
Unlike the chinese vise, there are no pockets, hard bits or trash in the cast iron. Even tapping into blind holes was straightforward with lots of consistent, tiny chips. Also no bondo/filler under the paint like the cheap one! It's bolted to my bench for now, I really need a cast-in-situ rebar and cement or hot rivet H-beam construction to mount it on. Maybe some 50x100 box if I can find some.
