Headliner is falling down in dodge pickup, what kind of adhesive do you use to repair it..?

Do yourself a big favor and take it somewhere to get fixed. A person can do it themselves but it can be very tedious and certainly very annoying.

If you still want to try doing this they make several spray adhesives that you can get at any car parts or fabric store.

Go slow,clean the surface thoroughly and good luck!

get it fixed somewhere....taking a risk doing it yourself and then could end up worse and still having someone take care of it.

You Don't. You have them replaced.
