?I was wondering the same thing.? Mine has had a few bits of dust under the display cover since shortly after I purchased it and I have been wondering if the clear cover?
was easily removable.
I am thinking that maybe it needs some sort of rubber gasket.? It might be possible to 3D print a very thin gasket out of TPU filament (very flexible). Maybe I will look into this as a fall project.?

P.S. FWIW this little rig has become my got to winter POTA rig. I have used mine for a few outdoor winter activations in well below freezing conditions and have no issues.?
