I bougt a roll of PET tape from ebay just to try it out, and god damn how well the abs sticks to it, almost too well, i am now printing a 180x180 mm print without any signs of lift in the corners, this is with bed temp at 110'c and a 40mm fan constantly blowing at the magma hot end.

beware that you will need to wash the taped bed with acetone before printing to get fat\oil residues off.

Highly recommended to try, you can get it pretty cheap from china.
