Matt, I am not sure what you mean. Can you elaborate?

Roger, the 3 bath kit has no stabilizer or final rinse so there may be problems. Both Kodak and Fuji use some form of final stabilization along with a type of photo flo.

And yes, C41 color neg was a re-invention of color film from the ground up. E6 did not change as much but it was still a rather large leap forward.
