Yea....I didn't realize it was that bad. IF it was me; I would look into using "super-glue" as a sealer. It works, it is simple and cost effective There was another thread with some links to working with it for the 1st time: I'll find it and post it up here.
Basically you just have to be neat and tape off the EDGES all around the head stock and a clean line at the back of the neck. You obviously could use a polymer but it could also crack - it's not nearly as strong as a cryn-type glue used as a finish. A few drops now to hold any peeling down would be a good idea. Do that under pressure. In other words use some manner of pressure on the areas that appear to be peeling up when gluing. It must have really got whacked. Here is one with wood & the basics:

I have personally used it. You want to work with viscosity of the glue (the standard glue) as it comes is thin; thicker viscosity samples for wood finishing exist in wood finishing place like WOODCRAFTERS. The thicker stuff may be easier to work with in the situation you have there.
Good luck; take your time, it's likely to work well.
