I don't have a rock solid engineering analysis but I do work as a mechanic and have balanced many tires. It sounds to me that these dynabeads have to be somewhat fluid to be able to move around the inside of the tire. From experience any liquid in a tire, whether fix-a-flat or water, always unbalances a wheel. It may not be enough to detect while driving but the balancing machine definitely does. Furthermore it always seems to collect on the "heavier" side of the wheel making the balance worse.
