Hello Kerry,
This was an interesting post, since the flightsweep hub on my '59 Imperial is worn to being very shiny on the lower end where water sat. When I got the hub I cleaned it with CLR to get rid of the lime deposits, and heavy staining on the lower end, but the brush finish was worn off. Can I use the same technique of sanding with WD40 to bring my brush texture back? I think the '59 hub is stainless steel.
