I don't remember that product, but I do remember one in which you'd unscrew the valve core (yes, there are, or were at least, presta valves with replaceable cores) and squirt the goo into the valve. There were also replacement valve stems with removable cores you could use to retrofit tires with single-piece valve stems. I think maybe Palo Alto carried these?
I also remember the goo as not being particularly healthy for pumps...
