I am not sure what you are trying to end up with but I wanted to mention this product.
3M 5200. Its an adhesive caulk. It sticks to everything and is like rubber when cured (in 7 days)
It is very expensive.

This is no ordinary adhisive caulk, its murder to get off. Its the best thing of its kind I have ever used. Its weather proof too.

They use it in the marine industry.
