Hi! Bought a 2018 RDX with tech package. Attaching a picture of broken foam piece that goes around the spare tire stabilizing it. Any idea what I can use to glue this foam piece back into place?

It also help hold up the rubber part of the floor right near the entrance of the trunk, so without it that piece is popping up. So it would be good to fix.

Also attaching pictures of a piece that seems to have come off… any idea if it’s easy to put back on? I tried briefly and could tell I was not understanding something.

Any help would be appreciated!

What can I use to glue this foam piece back into place? I see what looks like a yellow foam/glue that it looks like the factory maybe used. What is that?

Not sure how to reattach this.

Anyone know what this is? Was sitting in the trunk area.
