I am considering buying a 30# bag of micro ballons (the redish brown bulking agent). The cost is about $400.00. Even on my project that is to much. I can use about half of the material. Any one out there that would like to share in the remaining 15#? I could bag it to suit now ever many people want some. Let me know if there is any interest. For reference, a 5quart tub from Jamestown cost 40.00 and weighs just over a pound.
