First full run on my ABS clamp part using glue stick on the glass bed, used hairspray before with some lifting and curling. The part stuck like crazy and released when it cooled. Very pleased with the results. Easy, cheap and no fuss.
Hair spray has worked well overall since I just spray the whole glass and with PLA I can do a number of print runs before cleaning the glass and re applying. Will do another ABS test today on a couple larger woodworking gauges which will fill almost the whole build plate.

PEI sheets come today also so that will be another test to see how it goes but so far glue stick has been promising.
