Vision Miner Nanopolymer Adhesive (50 Ml) - Ultimate 3D Printing Bed & Building Board Adhesion - No Mess, Non-Toxic, Works for Pla, Abs, Pei, Peek, Nylon, Pc and More. Easy

First, the good stuff. It works. Prints stick to the bed, and then get unstuck relatively easily after cooling down. For the most part. I have had a few occasions where scraping was necessary but that’s to be expected with some materials. The bad: mainly that applying the product is extremely awkward. The way they tell you to do is by drawing a cross and a circle covering the print area, then using the included brush to spread it. The “brush” is a tiny one, with half a dozen stiff nylon bristles. The adhesive is very liquid. The brush barely spreads it over a centimetre - it has no chance to spread it over the bed. After a lot of frustration and asking other users in online communities, I settled for diluting the NPA with 1:1 isopropanol in a spray bottle. 2 whiffs of that over the bed, then spread with a microfibre cloth. That works well and lasts many prints!
