Hello, the fabric was completely shot on this headliner, I pulled it all off [with liner in place] then removed the tacky glue residue with the vacuum at the carwash. I was trying to get around not really dealing with it right now but still have the benefits of the insulation. However, I notice it flakes off dust which I presume is fiberglas? Can't be good for the ol' lungs. I'm dealing with it again as I am working on the windshield. Removing the door garnish revealed some more of the old glue [see pic]. I wondered it there was something I could spray or brush on the headliner to more or less seal it without removal. The alternative would be to pull it out and discard, start with some modern materials at a later date. Can't really get into it right now, I'd have no place to store it, and once it's out starting with fresh materials seems like a more appealing route. The van has been gutted to use as a work vehicle. Leaving the bare headliner in seemed like a good idea to keep its insulation properties. Not so sure now though. thanks for any thoughts or info!
