Please don't wax a surface smoothed only with 0000 steel wool, as there are still minute scratches on the material, not readily visible to the naked eye - for the best results, the horn should be polished after the steel-wool treatment.
I use the EASY button, polishing with a polishing compound on a felt wheel mounted on the shaft of a bench-mounted electric motor mounted - but I suppose the polishing can be done manually with an automotive rubbing/polishing compound & elbow grease.
