As a final, simichrome can put on that final mirror to chrome, but if rust has to be removed, I would start with a more basic product, Even a brillo or S.O.S. pad, as the soap acts as a lubricant to avoid scratching. Simichrome mated with a buffing mop (I use three abreast on a bench grinder works wonders,,, the bench grinder does not have too much horsepower and mass, so overloading to where the surface shows marks seems to be avoided. I brought a much zig-zagged Campagnolo superlegerra seat post back to presentable life with some wet dry sandpaper working wet and stoppong at 400. Way back this was the only post prior to Super Record with a "mirror" finish from Campagnolo.. and almost the same weight as a Super Record, just no fluting.
