Sanding out scratches on aluminum.

[scudo]

This is 2 I have renovated (before and after pics), I hand polish for deep scratches and then polish on bench grinder wheel.
Images 1 & 2 are an earlier model and
Images 3, 4 & 5 are a G5 that was in a heck of a state.

One solution to bring up that blue rubber trim is to use
Silvo® Silver Cutlery Polish (less aggressive than Brasso®) or Abro® Headlight Restoration Polish to remove fine scratches and smooth-out imperfections.
Follow that with Kiwi® Blue (Scuff) Shoe Polish, or blue Leather Furniture Renovation Cream, or add a few drops of blue Leather Dye to Caranuba Car Wax. The dyes will seep into scuffs and blend blemishes. The wax hardens to give a smooth, polished, durable surface.
