Developing slides in C41

[Bliz]

I'm tired of my E6 kits color dev going bad before I even used half of it, last time I tried topping the bottle with argon but part B went bad no matter what after a month.

So I'm now experimenting developing ektachrome with XTOL as a first developer and C41 chemistry after. The point is, does anyone know if there's a relatively easy to obtain chemical to do the reversal/fogging step? Having to get out the roll and manually expose it to light is a pain, and I remember reading somewhere you can buy chems suited to fog the film but I don't remember where or what they were.

Any hints?
