Again, I have two humidors, the larger made by Bourbon St, solid and well-made. All I had to do to bring it online was seasoning. The second smaller humidor has been much harder to make ready, plugging all inner seams with food grade silicone and then, so far, two hours of applying blue masking tape. When I first taped I simply applied it to all of the inner rim. As it still wouldn't hold humidity, I've been testing the joining of the outer rim with a business card, spot-fixing where needed, a layer at a time and then testing again not only the spot but the rest of the seal to ensure that I'd not caused another problem by the just applied spot fix. But the front still needs attention. In some places I have as much as six layers of tape.
I've probably tested it for two weeks with the wet sponge about four times.
The answer should have been to just chuck it at the start, being cheaply made and small. But this far in, I might as well go the distance; plus, I've learned a ton in the process
