                  This is a good product with virtually no VOC's. I have used many tubes of this when it comes to sealing ducting leaks or installing collars/couplers/and adjustable 90's. If you are doing a full system and installing ducting to start collars, building plenums, or sealing registers, I'd recommend the bucket of this same sealant and a paintbrush for the application.
