I print on a glass build plate coated with Elmer's glue sticks (purple). It works for PLA, ABS,and Nylon. In the past, I have had issues using kapton tape, painter's tape, hair spray, ABS slurry...even tried rubber cement. My success came with using the glue sticks. You just coat the glass with a thin layer in your print area when the plate is cool and print. After printing, it pops right off after the glass cools and it washes off with water easily for the next print. Gets ☺☺☺☺☺ rating from my experience.
