Thanks for the help. The thick wet layer is working better. I didn't let it dry like mentioned in the video, but it did go through the preheating of the build plate and extruders.

I'm noticing some curling in the corners of the PLA. Would this suggest that the hair spray needed to dry more or that I need to raise the build plate temp? I think my firmware version limits the build plate to 120 deg C. Probably fine for PLA, but might be low for the PC or PETG I've been experimenting with.
