Oh, just enough to scratch up the rubber to key it so the paint sticks.
I used fine wet&dry, can't remember what grade though.

I'm thinking that the finer side of an emery board would be the roughest
one would use, right? This seems even better than rubbing the pads with a
soft pencil -- less likely to wear off. A couple more suggestions. Chemtronics sell
(sold?) a rubber keyboard
repair kit. It was a 2-pack thing that you mixed and then put a bit on
the conductive rubber pad. The problem was that it's expensive, and once
mixed you have to use the whole lot (enough for about 100 switches I
think).
I found, while repairing mid-80s synthesizers, that roughening the
rubber bit with sandpaper then painting on silver-loaded paint (from
Halfords, the stuff they have for fixing heated rear windscreens) worked
just great.
