My experience on this issue is, I now use kapton tape on my glass bed, ABS sticks great, the trick? have 2 (or more) glass plates,
when first one finished, lift the model and plate off the bed, and leave until COLD, model then just falls off plate with no effort, fit another glass plate if you need to be printing something else,

I am getting 8 or more prints off the same kapton covered plate using this method, never looked back since I converted to glass bed with kapton!
