if a few of them are starting to go, then its likely second handies will do the same- especially removing then re installing...

I called a couple of motor trimmers who both confirmed that once the material begins to sag there is no effective permanent fix. The same information is also widely available from the web pages of motor trimming shops around the world.

The issue is that foam backing on the headliner (rather than the headling fabric or the adhesive) breaks down after a time (8-10 years seems to be the magic number) due to heat cycling, thereby leaving the adhesive with no attachment point.

Since the foam liner on the headling material is the culpable agent ( not the adhesive nor the headling material itself) a reasonable question to ask is why does the car industry bother with such a delicate (crap) solution? The reason is the foam headling, it seems, produces a more professional finish and it is by all accounts much easier to apply. In addition to the foam lining adds some heat and noise insulation to the cabin roof.

The fix options are:

  • go OEM or equivalent foam backed headling fabric. This stuff runs out at about US$16-20 per lineal metre.

  • go OEM quality foam backed headlining but in a different colour, texture or pattern. The sky is the limit here. One can have pretty much any colour or texture or pattern including: metallic, camo print, tiger print, snake skin... up to and including a... Union Jack. The price is about the same as the standard stuff.

  • go foam backed (Not Alcantara) suede or faux leather. Again the price is about the same as the standard stuff.

  • go Alcantara. (as per Bentley and Ferrari).. which is approx AU$100 per lineal meter. (Our cars need about 4 meters). Note Alcantara is available is suitable weights for headlining, however, the materials is not foam backed and it may or may not need additional foam backing.

why would a headlining need 4Lm? is the width of the fabric less than the width of the roof? if that's the case then it would need a join in the middle.

Mine's doing this - started along the top of the front windscreen - been putting off doing anything as my handsfree speaker mike was sort of pegging it up and preventing it from sagging right down obscuring my view. But cleaning the car a few weekends ago - noticed near the top of the rear window it was happening as well. Yep - definitely the backing foam is decaying - crumbles aways when I touch it. And I wonder why bother using such material which necessitates remedial action 8-10 years down the line. My car is BA '04 so smack on 10 years :nono: Guess it also depends on how the car is stored - possibly if it was garaged all the time - that might help extend the life of the roof lining backing foam.

Anyways - I've just tried using some ordinary household Selley's Exterior rated PVA glue - applied it with my finger. See how long it lasts. Maybe I should have used something that would have reacted with the foam to fuse it more to the lining having read the above and other threads. But sounds like I'd be repeating the gluing again after some time. Won't be spending money on a new roof liner - not yet anyway.

Probably not a good idea to use Selley's PVA. It's holding up the lining but I can see where the glue has come through the lining. Fortunately - I can't see it where it has come through from my driving position. I don't mind as it's less expensive than changing the whole roof lining for the moment though :dontknow:

The fix won't last as the lining drops as the foam fails so gluing it back to the failed foam = more fail.

FWIW I recently got a headlining renewed on a BA cost $320, took aprox 4hr and looks fantastic.

Black headlining FTW (plus painting the pillars)
