I've been using borosilicate glass for a couple of weeks now. I started with Aquanet just as others have. I found it messy and sticking too well with ABS even when cooled down. I've gone back to the standard glue stick. This is working great for me. Clean up is a breeze with soap and water after 2-4 prints. BTW, I use one large binder clip with corner clips. The top "handle" of the binder clip is bent down to provide clearance from the stepper belt.
