Bummer, Flippo! Thanks for the heads up on the product. I've never used this type but based on your experience, I'll be forever wary. I use a damp sponge in a perforated soap dish inside the case but outside of the guitar which has worked well for years.
I'm wondering if the guitar is allowed to slowly dry out in the affected area whether the joint will smooth out. If not, a little hide glue and strategic clamping could restore it. The nitro is another thing but I'll bet it can be repaired without notice. Hopefully, David Collins will chime in...he's our resident expert on these types of issues...I swear he's seen it all.
Now, take a deep breath, leave the guitar in its case with a humidifier and let the Super Bowl take your mind off the problem for the day
