I have for the past week been printing using PCB lacquer as a coating for the printbed ABS at 80c and PLA at 60c the items stay in place till cooled and are dificult to remove when warm. One coat has lasted a week so far over 3kg of mixed filaments and not looking like its going to need replacing anytime soon so if like me you have some around give it a try, if not this is what I am using

It is by far the easiest and cleanest solution I have found and works out cheaper than anything else if you account for time and effort in cleaning and coating bed, no residue on prints and no problems so far with PLA, ABS, NinjaFlex 30c and Soft PLA 60c.
