hey guy, i got my headliner out and the old fabric off and what not, but as i was taking off the what was left of the old foam, it took what looks like the first layer of the headliner board. What should i do, will the adhesive still stick?

I think you should be fine, just use plenty of adhesive so it can soak into the board.

A search will come up with loads of stuff about headliner repairs and there are a few tech articles

It's best to use a firm bristled brush to brush off all the old foam. It should brush right off very easily. What you'll be left with is a yellow/orange-ish surface. The spray adhesive will stick to that surface very well. From the sounds of it, you already took that top layer of yellow/orange material off, but as long as you've still got a flat, relatively smooth surface to work with, you should be just fine.

No. You don't need to use a lot of adhesive. Just an even coat is enough. If you use too much it will get into the fabric when you put it on and cause lumpy/wavy areas. It won't soak into the board.
I did the same thing when I recovered my headliner. Had the advantage of knowing someone who did car interiors for a living, they said rubbing the foam off with a stiff brush was the best way, but that peeling off the top layer of fiberglas (that's what the yellow material is) would work just as well. The top layer on mine started coming apart when I tried to rip what was left of the fabric off the foam, so I did it that way.
