Headliner board question

If it's a foam like material, don't do what I did! I had the same issue on an '89 VW GTI except mine was worse. I thought that I would reinforce it with fiberglas cloth and resin, it melted the foam! D'OH! Had to get another board from a junkyard and recover that one.

In fact, that may be an idea for you...

I think what I did with the junkyard board (which was better than the one I ended up ruining but still had a few trouble spots) was to use two-part clear epoxy to fix the trouble spots, reinforcing from behind with brown paper soaked in the epoxy. With the VW ones though the problem was cracking, not holes and thin spots. I am guessing that your cloth had not completely come off the board, and the thin spots are where some of the foam came away when you pulled off the cloth? I don't have any brilliant ideas as to how to fix that, but you should, or the finished product will show those spots.

No.

Good ole duct tape.

I couldn't tell much from your video. What I'd do is make sure all the old foam backed material is removed from the board. Then for the weak spots/cracked spots paint over them with some polyester resin, just a thin coat. If you use the proper foam backed material to recover the board I don't think you will see much of the imperfections. I recovered one board in an S-10 so I have very limited experience. The only problem I had was I put too much of the spray adhesive on and it was just too much in a few spots and bleed thru the foam making the material "sink" a bit in those areas.
