I can't really tell from the Q&A or reviews: Can you apply it to one piece out of water, then mate it to the second piece underwater?

Yes you may........but here is the issue, all glues of this type have a tendency to scab over and it lessens the bonding to the surface. You need to add enough glue that once it scabs you can still put it in the water and break that scab as you try to fasten it to the rock or what ever you are trying to adhere to. Of the glues I have tried to date, this one has a fairly descent response. This site has a good video on the different glues and how to apply them: www.bulkreefsupply.com/

Can i use this to glue my aluminum led light brackets to my plastic tank hood?

It is the exact same thing as super glue, except it's a somewhat thicker, so it should work for your application. However, I have found in doing customization on my aquariums that silicone sealant does a much better job of adhering pieces together - especially when of different materials. Hope this helps.

Can this be used to adhere a pvc pipe inside a rubber grommet?

This is gel super glue. Silicone may adheres to rubber better than super glue.
