I did a redneck restore on mine.
For the metal spokes - they were dirty, scammer, corroded, and stained. I taped off the leather & carefully cleaned off the metal with Simple Green & Speedy metal polish as best I could. Used some steel wool like 'grass doctor' said.
I stole some of my wife's old sand paper like finger nail files and a metal nail file that had abrasive all the way to the end. I used these to begin the brushed metal look under the edge of the leather. Slide'em under the leather. Apply pressure and pull parallel to spokes. I worked slow & it turned out fine.
Next I tried small squares of semi- medium sand paper (different grits) on a scrap of aluminum to see if I could reproduce the OEM brushed look by working all in one direction. That worked. The spokes turned out close to OEM - most TR owners probably wouldn't notice.
