Brian Kliss explains how he uses FastCap’s Sealant Savers in his work van. The Sealant Saver was developed by a cabinet maker to prevent caulking tubes from drying out. Simply fill the tube with water and place open caulking tube down into the Sealant Saver tube. The Sealant Saver creates an airtight seal that prevents caulk or silicones from drying out. It easily mounts with screws to any surface.
