How big of a print are we talking? I've printed large blockish items on an 8" (200mm) square bed with the purple gluestick with good results (100c give or take, I don't have control of that). I lay it on thick on the corners, seems to hold well. Then when I have to remove the item, if it's being obstinate, I'll soak the edges with a little water, and that loosens up the glue. Make sure the bed is completely cooled first. I can then remove the glue from the part with some water and cloth.
