The only time I've used a wetting agent, in a developer, is in printing. I was experimenting with the Winchester formula. It is very simular to Dektol, except for adding a wetting agent. I quickly learned that it had to be a Non-ionic wetting agent(e.g. Edwal LFN). Every time I added Photo-flo to Dektol, I would get a tar like substance floating on the surface. The formula prove no better than plain Dektol.
