Peeling at joins

[BurningSmell]

Hi folks,
Just a quick one. The tape/material that I’m assuming covers natural joins is peeling on most of the inside of our caravan.
It’s 20 years old so assuming it’s just lost its stick over time. Am I ok using glue to try and get it flat again. It’s more or less every piece and just has a bad look when on the whole the inside is very well kept for its age.
Thanks

Very common with age. I've reglued parts of mine. Contact adhesives have worked well. If it is very bad you could start again with new tape.
Just be certain the detachment isn't due to water ingress
