100 ml bottle of Vector 3D Spray adhesive for 3D printers is used on the bed build plate to eliminate warping and make prints stick. It greatly improves bed adhesion and eliminates the headaches of failed prints.
 
One light spray coat to the build plate will last for multipe prints so this bottle goes a long way.  You can add another coat if more adhesion is needed. This Vector 3D adhesive also cleans up easily with soap and warm water and has very low odor. The best thing about Vector 3D is it is not messy like glue or other adhesives, plus it leaves little to no residue on the prints.
