    Good for only one application
    The overall value of this product is low. After the first application, the foam hardens in the applicator rendering it unusable. Despite what the manufacturer says, there is no practical way to clean the applicator tube and trigger.

      Must use it all at once. Although it claims to be good for multiple uses it seals the can once it gets dry.

      Great Stuff™ Insulating Foam Sealant will seal itself shut if left sitting after use. Inserting a pipe cleaner sprayed with oil lubricant into the applicator straw may prolong the life of the product up to 30 days, however, it's better to plan ahead, identify, and list all possible applications before using the can.
