Don't know about a compass, but I've tried double-stick foam tape on
other cockpit items and found that it comes loose in the summer. A
car-parts place might have something ...

Car-parts places have the special glue used to stick rear-view-mirrors to
the glass windshield.... it works "okay" in the heat, but it is normally
used on metal-to-glass, and I don't know how it would work on plexi.
