I am now using glue on my strangely affixed creality glass bed and it seems much better than hairspray. I think I’m quite happy that I don’t have clamps to run into and I can keep the glass clean now with water and not alcohol. It seems quite indestructible from just being scraped unlike the original flexible magnetic thing it came with. Ender 3 pro. If I have prints that are stubborn I heat the bed to 100 C and they come off with a scraper. I see no need for a heated bed with PLA.
