We have a metal tubular vent for the chimney exhaust from the fireplace, which where the vent pipe exits at the top of the chimney, there is a water leak on the outer part of the metal vent. What appears to be caulking has lost its seal. Can I use this product to seat this area on my chimney or would something else be better to stop the water leak?
