Best Self-Leveling Sealant For An Aluminum Roof?

I have a Vinyl roof and use Dicor. I would call them to see if they recommend it on Aluminum. One note about Aluminum. I had a Class A once that had an AL roof and it developed bad leaks and pin holes. Seems the manufacture installed the AL over steel without a barrier. That caused electrolysis in the AL causing failures. Be sure your RV does not have that issue.
