    Default Styrofoam Adhesive

    Guys,

    My Scenic is suffering from the dreaded "C-Pillar Sag" that needs to be remedied.
    I need to reattach the cloth but have not has any luck finding an adhesive for the task.
    Obviously it can't be a solvent-based adhesive (that will dissolve the Styrofoam) so that rules out the majority of the common adhesive. Of the water-based types, I've tried a few (PVA and starch based) but they either didn't hold at all or for a few minutes only. Has anyone done these before and was anything successful?

    The C-pillar trim in these fit from the back door to the hatch aperture and are a bit of a PITA to remove.
    The trim fits from the top down and from front to back so one has to strip out the boot trim, and the bottom of the C-pillar before you can get to the top C-pillar section. While it only takes about 30 minutes per side once the boot's empty, but the clips often break so you get rattly trim afterward so gluing in-situ would be preferred.

    (Yes, I guess I could take it to a motor trimmer but thought I'd try first)

    Cheers

    I was going to suggest a sikaflex type product, but that looks better. I've had great outcomes with sika products generally.

    Have tried to fix sagging head linings for years.
    Never looks quite right after.

    Get a motor trimmer and he might be able to reuse what is there.

    Any attempts to fix will not allow this happen

    Just had my Scenic the whole hood lining redone by a trimmer. Cost $260. I guess a C panel would be less.

    I don't know if this would work as a repair 'in-situ', but 3M make a spray contact adhesive specifically for fabrics. It sprays the adhesive out in a spider-web type of pattern. I have made a new headlining for a car using it, and it was perfect. Sorry, but I can't recall the exact name. It was one of those 3M numbered products.

    Regards,
    John

    G'day,

    a lot of headlinings have a foam backing which disintegrates over time, leaving a powdery mess. Whilst you can squirt glue in there via a syringe the powder tends to mess things up and the repair fails.

    Depends on how fussy you are, in the ute I've just fixed the headlining back with some dressmakers pins obliquely into the cardboard sound deadener. Works quite well, so who studies the ceiling when they're motoring along ?

    cheers,
    Bob

    Hello Bob,

    It's not the headling and doesn't have sponge-foam under it.
    The cloth is directly onto very dense styrofoam-like material.
    To complicate it further, there is an airbag under the top edge of the panel so it can't be anything too good otherwise the airbag might not deploy properly. Not that I'm planning to be T-boned anytime soon.
    The airbag could be why it is only loosely applied at the factory.
    If all else fails, one could strip-off the cloth and paint it a nice light-grey. with water-based paints of course.

    Cheers
