Personally I would take the whole thing down and recover it. I did mine a few weeks back and it's not hard work at all. But, first I would make sure you have the fiberglass headliner as I've heard the cardboard is a huge pain. And unless it's made for headliners I personally wouldn't use the Elmer's stuff.
1) Purchase new headliner material. I got mine from Hancock fabrics (specifically labeled for headliners) and it is already foam backed.
2) Purchase headliner spray adhesive from the parts store. I used the 3M stuff for lightweight headliner. I was afraid the heavy duty stuff would soak through.
3) Take old headliner out of jeep
4) Remove fabric from old headliner.
5) Scrape off foam/adhesive residue (if you don't have a grinding wheel with wire brush, I found an old grill brush with wire bristles worked well).
6) Cut new headliner to size.
7) Follow directions on spray adhesive to recover. It's not difficult at all to avoid wrinkles if you aren't trying to do it still in the Jeep.
8) Reinstall headliner.
This should take approximately eight beers to complete.
Total cost for me including material and adhesives (I used three cans) was about 50 bucks... but I did have a 40% off coupon for the fabric.
