I did use abs glue on glass - works okay, but having to repaint after every print is a pain.

never got round to trying the hairspray - although I did buy a can from poundworld :-)
As long as it lists pvc (think that's it) as one of the first ingredients - it should work.

It was around that time I switched from a flat glaass plate to a flat aluminium plate and from abs to pla.
And then wondered why I'd ever believed all the stuff about abs versus pla in the first place :-)
