Go to a local glass store and get a 8x8 mirror. I get 2 just in case I needed the second...and I'm glad I did! After warping (even with tape, ABS sauce, Elmer's glue), I applied a VERY thin coat of Krazy Glue with a brush applicator; making sure it's not too thick anywhere. I then spray it with extreme hold hairspray (I prefer Suave because of the smell) and let sit dry. If a print, when completed, is firmly stuck to the mirror and is difficult to come off, you simply remove the mirror and set it aside to cool off for about 20 minutes and slide the new mirror on to keep printing.
I have ZERO curling and the mirrors cost me about $8 from a local shop that appreciated my business. After removing the prints, it is not necessary to reapply. I'm going on 30 hours without any cleaning. Since it is glass, the Krazy glue comes off after a hot soapy bath with some scrubbing. PLUS= you can use the mirror to see the underside of the print!
Glass/mirror are highly recommended all over Soliforum.
I use no brim using this process.
