I don't think the plastidip will work as it only leave a thin coat and the handle are 16mm 5/8 thick around a 8mm 5/16 steel bar. I tossed the idea around at work today and the consensus was its a special bending jig. so Unless anything springs to mind I'm going to case it in Onyx over a greased handle so it will still spin. not ideal but I need to move on. I made a jig for bending the handles that works way better than I was expecting.
