[merkit the grof]

I am not at all sure it does clean the track, the CM track is gloss, it doesn't visibly rubber up, there is nothing for the silicons to pick up.

Silicon itself might be inert, but there is no telling what additives have been thrown into the mix during the manufacture of the tyres. On the day, Don Siegel said that it was the modern silicons that were the culprits, but, if that was the case, the old timers who came across silicons in the 60s wouldn't have such an aversion to them.
I don't think 1 driver would make a massive difference, what happened that day is that all bar 2 drivers used silicons in the thingy race.
