07 S60 Sunroof will not close

[T64me]

I bought a used 2007 S60 AWD a couple weeks ago. Today, my daughter drove it and opened the sunroof. When she tried to close it, it would only go about 3/4 closed. When the sunroof on these cars is opened, a "wind blocker" pops up in the front (not sure what to call it). Whatever that thing is called the bracket that holds it in place on the passenger side has come loose. This bracket was originally glued in place with a silicone type glue. I have a few questions:

I removed the entire wind block and loose bracket. I figured with this removed I'd be able to at least get the sunroof closed. Nope, it will only close 3/4 way. Any ideas as to how to get it to close all the way? It is supposed to rain all weekend...

My HOPE is that if I glue the bracket back in place and reinstall the wind block device then the sunroof will close. Does this sound accurate?

I know I will have to clean the area with lacquer thinner before re-gluing the bracket in place. Can anyone suggest what I should use as a glue and where I can get it?

What type of grease should I use on the sunroof tracks to replace any that is removed during this repair?

Thanks in advance for your input!
