Usage for chimney cowl to cap gap?

Can this be used this to seal around a chimney cowl to the chimney cap? I understand it has a 150 degC rating which should be more than sufficient for the two storey gas flue.

Can this be used on fish ponds?

Asked by: 44APB44
Hello, No, this is not marine safe and may harm aquatic life. Additionally, it's not suited for permanent submersion in water. I would recommend opting for a specific pond safe product. Thanks for using Q&A. [DG]
