so of course wishing the first month of bringing my car to Florida, the rear section of the headliner is beginning to sag. Any recommendation?

 

I used some of those twisty fabric pins and covered them up with an SRS insert cap in each rear corner of my E500 where it was sagging. Helped a lot and hardly noticeable.

 

I would recommend finding an upholstery guy, and have him completely remove then reinstall your headliner, that way it will not fail in the near future. You want a fix, not a temporary one.

 

 

I'm only being realistic, and this is exactly what I would do to my on car.
Why look at a temporary fix, find a permanent solution.
Spend the money and have it done right the first time.

 

 

Agree with full replacement. It is much less expensive than expected. I had it done on a SAAB.

 

It's going to cost way more than $100 to have an upholstery shop fix a sagging headliner. Lots of man hours to remove all the assorted trim pieces before accessing the liner, then the gluing and reassembly. That's why I went the route I did - maybe not a perfect solution but it looks much better than before with minimal cost and effort. Just my two cents.

 

 

Could you please let me know the headliner shop you used in case I ever decide to go that route. Thanks buddy.

 

I'd remove it and or replace it.

 

 

I applaud you for trying to save yourself some money, but it's better to have it done right the first time, by a professional.

 

I pulled the headliner from my W210. Major PITA since I had to take it out through the door. Remove seats, remove lots of interior trim pieces that tend to break (at least I installed quite a few nice and new plastic parts). I ended up getting the A, B, and C pillars re-covered to match the new fabric. The vents in the sunroof shade were brittle and also broke; located replacements in Germany. Not a trivial task. Removing the windshield would have made it much easier but I wasn't going to do that by myself.

Do it professionally if you do it at all but let them know to notify you if plastic parts break so you can obtain replacements. If not, a staple gun and 1/8" staples will work for the short term.

Start here for an idea of what needs to be done:

Mine was sagging in the back, I removed the headliner out the passenger front door, sanded the yellow foam off, sprayed 3m headliner adhesive, reinstalled, and it fell back off. I may have kicked something, said some bad words.
I then used contact cement applied to both sides instead, worked fine.
2 years later still holding up fine.
