Re: Glas Bed SD2
yes only need a thin cover of hairspray on one surface then place glass on sticky side lined up with bed (I also used emery cloth all around edges of glass to take the razor sharpness off to help prevent cutting myself during use)
then turn bed heater on till it reaches temp (SD2 takes several mins for this each heat up cycle) once temp is reached turn bed heater off and let cool to room temp. repeat this 2 more times and it will stay for long time unless lots of sideways force is applied or pried on and broken. I have printed dozens of items with mine that way and only had to clean or reapply glue stick some times which I use for good adherence of ABS prints. most prints pop loose upon cooling a few had to have razor slid under to loosen which took some glue stick off needing reapplied.
