White metal. Start sanding ( i prefer Tamiya sand papers) 180 grit, 240, 400, 600, 1000, 1200, 1500 and 2000. Then i use these polishing pads i inherited, 3200 up to 24000. I've tried also using polishing compound but i didn't see a significant difference to the finish....it's the 24000 and the 18000 that really kick in the shine.
The real problem comes with deep pitting in some of the pieces, then you have to really work at it with the 180.
