sorry, forgot to include that info.
I'm doing pt/pd with cold bath developer. I did a single coat for a 5x7 image using a puddle pusher. I used 7a 1b 6pd 3pt (this amount of coating was more than enough for the area). I dried the image with a hair dryer and then re-humidified for 90 seconds, flipping the paper every 30 seconds.
Another problem I noticed was that the coating was slightly sticking to the negative. There was a sound as I peeled them apart and a little residue left of the negative. This drying/humidifying procedure is identical to how I was working with the platinotype with no issues related to sticking.
