Re: RIP My 240; Whats the skinny on 740s
Not having done this job, I imagine that the headliner fabric has hidden
sleeves that slide over stiff suspension "ribs" fastened to car ceiling,
and/or the fabric is otherwise pasted up to the ceiling or stiff suspension.
Whatever the skeletal structure, a small needle puncture in the fabric at
the lowest sagging point of the drooping headliner will allow one of those
small plastic straw barrels to poke through, attached to aim a spray
adhesive (several 3M brand products and other brands) to shoot a thin and
spotty sheet of glue up between the headliner and its support system. You
may even have a few/several very small and unseen puncture points if you
have several droops or droop is very large area. When tacky enough to hold,
firmly wedge some flexible objects up against the headliner in several spots
for the recommended curing period. Pick a glue that does not break down and
fail under seasonal changes (record heat or cold temperatures in your area).
Mind you, I've not tried this. Prob'ly very unprofessional, but what do you
have to lose?
