Bill, I use a prewash all of the time, and my Jobo and Kodak manuals from years back recommend this even though it has changed. They use the prewash to bring the tank up to operating temperature, so they say to use 100 deg F.

Other than that, if your kit lacks so much information, the kit is not complete IMHO. Buy a better kit.

AFAIK, all E6 films require some sort of stabilzer to be applied to the film somehwhere in the process. You must have one for optimum dye stability.
