I use this brand, which I believe is more or less the same thing. It's very effective on really dirty records. Cover one side of the record with the goo, let it dry overnight and tear everything off in one movement the next day. It also feels very satisfying :)
I decided to go with the Record ReVirginizer once I found out it is an Australian product. The sole distributor in the NT is going to drop me off a bottle at home after work [saves me a bit of postage or a trip to town]
