Emailed MWS - said they are pre-waxed and ready for use - will use the Meguiars Ultimate detailer. Also MWS say their cleaning kit leaves a wax on the surface to keep off the brake dust - so will get some of that . I got the stainless for ease of cleaning/maintenance as the painted wires chip & rust easily.
Congrats - you all got in there before Mr W!! who may suggest protecting from dust with a spray-on neoprene.
