It's in either a quart or a gallon. go to like a Harbor Freight and get a cheap spray gun from them for like $20 bucks and use that to spary it. Then just throw it away cuz it's a B cleaning them.
Or you can get the spray guns made for contact cements and other glues for like $60 bucks
The best stuff to use is the kind that you have to spray from a paint gun.But 3M 90 is ok for flat stuff.Or Loctite makes some called headliner adhesive.Just make sure you spray both pieces and don't stretch it to much or it will pull away like FBI said.
