I've had a second headliner sitting in my garage for the last 2 years so I finally want to get it into my car. For things like doors I usually use a 77 Super Tack spray glue but that works fine because gravity isn't pulling against the glue like on a headliner. I'm afraid too much glue would seep through the material and ruin it, too little glue wouldn't hold it on there, it will sag.
Is there another way to hold this material up? It'll likely just be a fake suede from Fabricland.
