When i peeled the old headliner material off of the fiberglass board on my 1989 cadillac, ALL of the plastic film over the fiberglass board tore off, what do i use to replace it? Or will the new fabric adhesive stick to the fiberglass?
The nature of the film over the fiberglass makes it impossible to be replaced - so you have one option; put the headliner material on over the exposed fiberglass. It will go on good (stick to it good) and it will hold, but it will be a little lumpy, if you don't mind a little bit lumpy, everything should be all right. I believe it would be wise to use a little extra glue on the headliner board due to the loose fiberglass.
If you want to decrease the lumpiness on a headliner board like this, use 2 layers of headliner material.
