i love racing at kambah, i think they used some sort of tar emulsion paint, seals the surface, and provides a great base, i actually prefer when they dont VHT, but they do it for the noisy cars, otherwise they cant do a lap there.
i believe bob jorgo, was in qld for a little while but i heard rumours he is back in town, i hope he organises a big race soon, i know i will be there with bells on.
