A while ago, I posed a question on the Brunswick.com forums asking what the factory surface of the Raging Inferno is. Brunswick's Billy Orlikowski replied that it was 400-grit sand followed by Brunswick Factory Finish polish. I asked about the use of Trizact sanding material; Billy replied that Brunswick is no longer using Trizact (on post-Proactive particle, I gather), and that post-Proactive Brunswick particle balls are easily returned to the factory finish through the use of sandpaper or Scotch-Brite-type pads, and if needed, a polishing compound like Brunswick Factory Finish polish. He also said that in lieu of of the BFF polish, one could put the ball into a properly-functioning Lustre King.
I have resurfaced my Raging according to Brunswick's spec, using either a pad or 400 wet-dry sandpaper and BFF polish, and I've been happy with the results. The BFF polish doesn't "overgloss" the surface like some other polishes tend to do.
