STRONG Bed Adhesion with PVA/Weldbond

I have been having some issues with insufficient bed adhesion, especially when using some less than stellar PLA, so started experimenting with a variety of bed treatments. ABS paint, bluetape and Kapton all worked pretty well, but the new, all time champion is now PVA/Weldbond glue in an ultra-thin layer, only a few molecules thick, which gets the strongest (perhaps too strong) bond I have ever managed. This thin layer completely eliminates any corner lift, and prevents the tape from being pulled off of the bed as well. As a bonus, the heated bed doesn’t have to run as hot.
