My sunroof is leaking in my car. can i use this to seal the sunroof shut? i don't need it to open but i do need it to stop leaking.

Yes. I used this this to seal a couple windows and it worked great. I don't see any reason why it wouldn't work well for a sunroof.

Need to seal 3 cracks on top glass panel of aquarium that i plan to use as a terrarium.is it visible when it dries?don't want to see/feel any residue.

It may not be significantly visible, but it will not hide surface cracks of clear glass. Any residue can be cleanly removed on the surface with a razor blade. Whether or not it can be felt depends on the gap width. The number of cracks does not matter, but the type of crack does, and that was not described.

Can this be used instead of grout for ceramic tile installed outdoors, under a roof but exposed to weather, in Florida. Is it totally clear?

Technically you could but it would not hold up very well. This type of caulk isnt fond of direct sunlight or really cold temps. I have been waterproofing for a couple decades using every product under the sun. I am in a unique position to be able to go back years later and see how various products I've applied have held up in different conditions. For me I mainly use silicone sealants inside.
