Re: Lithium palladium vs. normal palladium
Witho, Somewhere in the back of my pea brain I remember someone, I think Sandy King, saying that when double coating, he had to increase his exposure time—could this be an issue with your DMax?

That is why I lack some Dmax, I think, just because I do not use enough sensitizer. I always double coat with half the strength of the sensitizer. It gives me lots of time to make very smooth coatings and cope with the hygroscopic effect of the lithium. So I go to 1.35 with 1 ml metal solution and 1 ml AFO 60% (single coat) or double coat half the concentrations. Witho
