For the past forty years Glessner Sales Incorporated has been the leading developer and manufacturer of environmentally sound architectural coatings for the paint and concrete industry. Chemists were developing safe water-born products as early as 1970. These products were created to replace and improve upon existing petrological coatings made with combustible, flammable, and even toxic ingredients. In 1991 a chemist at one of GSI's affiliate companies (Burk's Paint Co., Washougal, WA) developed an exceptional foliar anti-transpirant. The unusual properties of this film have allowed it to become the most effective of all foliar anti-transpirants. That product is MOISTURIN and is the flagship of GSI's new horticultural company, GSI Horticultural. Since the development of Moisturin foliar anti-transpirant only one other product has met their criteria for uniqueness and functional excellence. That product is ROOT-ZONE drench antitranspirant. GSI Horticultural is a DBA of Glessner Sales Incorporated, Bend, Oregon.
