Once the glass is exposed, use the chisel to scrape as much of the old glue as possible.
Note the gaps between the lid & the glass. No wonder this humidor leaked. I’m about to fix that problem
using fishtank silicone. I picked this tube up at PetCo, I think it was a couple bucks. It smells like solvent when it’s going on, but once it hardens the smell goes away.
I ran lines of silicone all along the cracks and beneath where the hold-down strips went.
I then repositioned the hold-down strips of wood, and clamped them with the 2 clamps I own. If silicone oozes out along the exposed glass, you can use a razor knife to trim it once it dries.
I did this on all four sides, leaving the clamps in position for about an hour before moving on. If I had more clamps, the job would have been done faster, but I wasn’t in any real hurry. I then reattached the woodstrips by pressing them in to the exposed staples on the inside of the lid.
