Good day.

My headliner is in great shape, having been replaced a couple years ago by previous owner. Only problem - it sags. Bad. Is there some tacky stuff I could purchase that anyone recommends? Plus, the liner is perfect conditon, I don't need to rip it out, and the foam above it is still good - they just came apart. I want to keep the liner intact, so telling me I need to rip it up to fix it is... well... not what I was looking for.

The best stuff to use is 3M spray adhesive. If you remove your interior lamp you should be able to spray the whole of the inside of the headliner without removing the whole thing. Unless you have T-Tops, and then you're on your own!

Thank you! Nah, it's a regular roof, no worries.

 

3M General Trim Adhesive or 3M Fast Tack Trim Adhesive will both be good for headliner. Good call with removing the lamp... I was going to suggest a heat gun to peel it off and do the whole thing over, which you may want to do unless you feel like repairing anything else that starts sagging in the future.

Do NOT use 3M spray Super 77 or 90! I'm willing to bet that's what was used to put your headliner on by the previous owner, and now you see the result.
