You're welcome! We here at JEC use ABS Glue. By the way, there are 3 types of liquid ABS mixtures used for adhering your prints to the bed.
ABS Juice is great for small parts, uses not too much ABS to acetone ratio. Recipe here.
ABS Glue is great for larger prints as well as gluing pieces together (or so I am told). For this, we take an old pickled okra jar and fill it with acetone (about 75% full of a 16oz jar) and stuff it with failed "air" prints, scrap extrusion strands, any nozzle flushes that we would otherwise throw out. Stuff the strands into the jar, close the lid tight, shake it, and wait about a day. Should be a whole milk consistency. Not an exact science with this mixture, but having more ABS in the mix seems to help our prints stick better.
ABS Slurry should be a thick syrup consistency (Think maple syrup, not molasses or honey. Elmer's glue consistency would be a good example). This you could make over a few days with stuffing the scrap filament into the jar until you get a nice thick concoction. I am told this could be useful for smoothing prints, filling gaps, making the object waterproof, etc. This may be a better concoction to use for gluing pieces together. Maybe someone else could elaborate, if they know from experience.
On the glass:
ABS Juice looks like a white film covers the glass in streaks.
ABS Glue looks like a canvas print. For us, we use black ABS. So our table appears to have ridges and black strands of ABS in a cross-hatch pattern on the glass. We pour the mix onto the glass and use a horse hair paintbrush to spread it out. Once you notice it start to dry out after painting it on, then it is time to take long smooth strokes from top to bottom of the glass. Then go side to side. If some areas are thinner than others, pour a little more out and repeat. It should look like a canvas painting does. You can, however, still see the glass through the mix. Maybe a pic would help here. I'll see what I can do. But if you use this method and mixture, I would recommend a raft. It will help even out the, now, uneven glass.
Never tried the Slurry on the glass. I'd be willing to try it though. We saw an improvement going from the Juice to Glue mixture.
Whichever method you use to print with (ABS Mixtures, BuildTak, Kapton, Glue Stick, Hairspray, etc), it is really up to you to decide which one works best for you. People swear by different methods, just try a few of them, or all of them. You aren't losing much by testing, but gaining knowledge in the process.
