Well, I absolutely cannot SEE or FEEL any cement, but I did mist the area where I thought it was, and sure enough, there's one area where the water will not penetrate the leather.
I put a bit of alchohol on a cotton ball, and wiped the heck out of the area. I let it dry, and it looks clean, if not a bit dry. So, I misted it with water, and the area that was resisting is now accepting moisture. I think (hope) it will dye okay.
