Is there a reason you are not spraying or selectively coating (e.g., Nordsen coater) your boards? Your labor will decrease, as will your defects. I would also suggest evaluating different solvents and/or a new coating if you must dip and are having too many bubbles. Humiseal 1B73-LOC worked reasonably well for me.
