I've yet to actually "rejeuvenate" the surface of my Intense, by which I mean oil extraction. I have modified the surface a few times.
Stock is 400 grit plus Brunswick;s high gloss polish. I wanted to use mine on a medium-light oil pattern. So I sanded it to 2000 grit. NG, no good for medium light. It grabbed VERY early on medium-light. (Might have even been good for almost heavy oil! (not really)). Then re-applied B's high gloss polish. Much better. It went longer and had a milder backend, suitable for medium-light.
Then I had a weight hole put 2" inside my PAP to reduce flare and hook; so I took it back up to the original surface prep.
Seemed no problem to go up and down the scale. Still needs polish on any condition from medium-light to medium-heavy. (FYI Nice to play an outside line on medium-heavy oil!)
I hope that's the sort of thing you were interested in.
Having it redrilled, so I can try to use the original surface on medium light: going from a 4x5 drilling to a 5.5x3.5 drilling.
