Thanks,
I'm not sure about the other products, as these are what I have used. For the naptha, it wasn't prepsol...it looked pretty generic, didn't even really see a brand name on it, but it worked just fine.
I'm part of the Porsche Club, which does AutoX and track days, and also the Northern California Racing Club for track days.
I haven't done SCCA or other things because A) I've heard the 993s are not super competitive in that area compared to some purpose built AutoX cars, B) not intending to sound like a snob, I enjoy racing other Porsches, as it is a bit easier to gauge my skill as a driver that way...eliminates more of the wonder about how fast the cars are relative to each other.
