In my experience, the plastic build sheets that ship with most of the low cost printers are OK for several PLA prints but the surface degrades quickly. The adhesive backing fails and the plastic peels off the build plate when trying to print ABS on a 110C bed, and that's a great opportunity to install a sheet of borosilicate glass over the tacky adhesive.
As I previously mentioned, a jumbo sized Elmer's glue stick can cover the entire bed in less than a minute. You only need glue where you're printing. You do not want a thick gloppy mess of glue. You want the thinnest uniform layer possible. It should look cloudy on the glass. Apply glue stick to the room temperature glass plate. After printing, ABS parts cool, contract, and pop off the plate. PLA parts come loose after a few minutes soaking in water, which you use to clean the glass plate between parts. The glue is easily removed from the build plate and from the part with water. No messy hair spray buildup. If you've struggled removing a previous print, you may have knocked the bed out of level. Problems removing a part lead to problems with the next part not sticking to the unlevel print bed. It's important to focus on the fundamentals when 3D printing. When it works, it works well. When it doesn't work, it seems that nothing works. A methodical approach will yield positive results. Getting in a hurry and putting the cart before the horse will lead to frustration and failed prints. It's similar to competitive shooting, where slow is smooth and smooth is fast. The fast path to 3D printing success is to slow down. Once you've mastered the fundamentals, 3D printing is much faster than CNC machining and the success rate is higher.
