I've avoided my normal; suggestion, so far :-)

Neutral cure silicone rubber sounds like a reasonable match.
It's not instant cure - for that use hot-melt to locate short term and
silicon rubber for the long term bond.

It is removable, depending on what area you choose to use.
Can be 'thinnish'.
Will ooze out under pressure unless suitably designed.

I recently tried to remove some aluminum L brackets from PCBs. Just what I
needed for a prototype. These were assembled and bonded 10+ years ago and
had been used as mechanical attachment plus heatsink to fram (exercise
bike).
They were fixed with 2 small screws (3mm, threaded hex but) PLUS silicone
rubber under the contact face.
After a small while I gave up an went and found some other Al material. I
could have removed this with enough effort but the bond was superb. This
was Al onto soldermask.

Hot melt is a good quick fix but will debond after months to a year if not
physically keyed.
