Great Product
This is a great product, easy to use. We had some areas on our HVAC system that had air leaks and it was easy to use this to seal up the air leaks. Does not work if area is wet! Have to wait until area is dry and product takes 48 hours to completely dry but it stays closed once dry. Overall great product and love the bag and supplies that come with it!
