Just make sure you only do small sections at a time though because once this stuff sets..If you have a wrinkle you're screwed..
Do you prefer to start from one end (and which one?) or hold the ends up and lay it from the middle outward?
One other key is to make sure you remove all the old foam backing from the old headliner..So you get the best adhesion possible..
I haven't peeled mine back yet, so I'll ask: is the '96 backer board ABS, fiberglass, cardboard fiberboard, resinated jute or something else?
I use a combination of a Brown Scotch-Brite Pad drill attachment, and a Brass wire wheel drill attachment..
Have you ever tried an adhesive remover spray? I usually use Chemtronics ES805, which removes just about every soft adhesive from just about everything.
I don't know how effective it would be on OEM headliner adhesive, though -- does anyone know exactly what Ford used? I'm assuming it's just some kind of commercial-grade contact cement.
The less expensive WD-40 also lifts contact cement, but is a no-no for a lot of plastics. I've used it on thermosets like Formica w/o harm.
The Chemtronics remover is safe for most plastics, and I think it would be quicker, easier and less risk of damage to the backer board than the wheels, depending on the backer board material.
Since the fingernail test says my OEM foam is toast, the spray would adequately penetrate it (as opposed to being absorbed by foam that's in good shape). Stubborn foam can be removed first via hand rolling, etc.
Maybe it's just me being overly cautious, but I have an aversion to using power tools on pieces like this.
However, if the backer board is pressed fiberboard or resinated jute, then I'd have to rethink use of a chemical remover, since it could be absorbed and soften the board, leading to warpage and degradation.
Actually, that brings up the question of whether the old adhesive layer needs to be removed at all. Would the new adhesive grab onto the old adhesive well enough if the old adhesive were thoroughly cleaned (and dried)? I guess it depends on what Ford used at the factory and what the backer board is made of.
