Dow Corning Sealant to use outside to prevent leak

Colour Anthracite means clear sealant? My application is outside between UPVC window perimeter and wall which is currently leaking after using over 10 years. I want to seal it against weather. Please advise the particular Dow Corning product Thanks
Asked by: Bhunu

is this heat resistant? I want a sealant to fit a chimney cowl
