A guide on how to apply Elmer's Glue properly.
Heat the bed to 70 C.
Lightly apply a THIN layer of Elmer's glue.
The lines applied showed by all consistent (either horizontal, vertical, or diagonal)
Wait for the layer to dry.
Repeat: Apply another THIN layer of Elmer's glue.
You should repeat the THIN layer application until you've done 5 layers.
Thanks to m3rc for figuring this out.
