I have several 50 pound buckets of Calcium Chloride available for $50.00 each. It is 99% pure pellets perfect for making 2 part. 50 pounds comes in the larger 7 gallon buckets. I can do 1, 2, 5, 10 or 20 pounds if you prefer at $2.00 a pound. Shipping would be at cost. Pm you zip code and how much you want, to get shipping cost.
