At the suggestions of some other posters I gave Aqua Net hair spray a try when printing eSun ABS on my borosilicate glass heated bed, and it worked wonderfully for some small test parts I made... a bit TOO wonderfully :|

It was an ordeal removing the parts (smaller than 1 square cm footprint), I was trying to get them to pop off using a razor blade scraper and I thought I was going to damage the print platform because of the force required.

Any tips for getting it to pop free? Do I need to remove it when it's still warm/hot? I let the part cool completely before attempting removal.

I'm a bit scared to move onto some big parts, I have a piece that has a footprint of nearly 6"x6" and I'm terrified it'll end up (nearly) permanently bonded to the glass.

I had very poor to mixed results using regular Elmer's purple glue stick. Sometimes it would work okay, sometimes not at all... I'd like to find something that bonds well, but is easy to remove when it's all over with.
