I have used both. There is no comparison. Eternabond last. Flex seal is a joke.


Completely Agree-- Not really designed for what your attempting but if it works, It will be with the Eternabond. I would take some fine sandpaper to the tank side to rough it just slightly to give the Eternabond some texture to grip. Randu


I agree. Contact Eternabond. They have a cleaner/ primer they recommend, I have used, and it made the difference in bonding strength on our"C".
