Rapid Cure is a 2 gallon kit that is packaged in 4 quart-sized bottles of "A" and 4 quart-sized bottles of "B." This greatly increases the useful life on unused product because your "shelf-life" meter doesn't start ticking until the bottle's seal has been broken. We have exchanged the pumps for "Yorker Tops" that also enhances shelf life and product quality. Pumps dispense fluids on the down-stroke and bring in outside air on the up-stroke. That outside air also contains any humidity (moisture) that is present in the air and as all of us who have time in the pro shop know: urethane and humidity are not friends.
Anytime you have had an issue with "foamy" ball plug, it is because moisture as been introduced into the bottle. This is why we removed the pumps and stress the importance of keeping the lids on the "Yorker Tops" securely in place when you are not dispensing ball plug into a mixing cup. Rapid cure is packaged under controlled conditions to insure that no moisture is present in the bottle when we seal it.
