peaked aluminum roof sealer

You have leaks in an aluminum roof? Do you know what is leaking or where? It's certainly not the ntire roof so figuring out what you are trying to seal is very important.

That's what I would use, should do the job just fine.

That product will work just fine. If there are cracks in the factory applied sealer tape, you may want to remove it, clean the area, and apply a new strip of EternaBond tape. The sealer that you found is fine for any of the other roof penetrations.

What are you needing to seal? Is there something wrong with your roof? If vents and other openings it seems the most widely suggested item is eternal bond tape and Dicor self leveling sealant.
