From reading some of the previous posts it appears that many if not most people do not recommend drying with a hair dryer. I guess I was trying to be true to what Dick Arentz recommends in his book.

I think I will try what Dana recommends and coat the paper either with water or and oxalic acid solution, and once coated with sensitizer, will let the paper air dry. I will also try to crank up the rh in the corner of the basement in which I work with a humidifier.
