Headling "stiff"

[utey]

I noticed the headling on the ute is getting hard and feels like it will crack if too much movement also it seem to be shrinking??
This is happening to the lower corners of the rear window.
There is a slight water leak which has caused the problem.
Is there any product I can use to soften the material?
Acetone comes to mind?
Any thoughts.

i think acetone will disolve your headlining not just soften it.
ps. ive been known to be wrong before though.lol.
