You are asking for the best and fastest, the best to me is the strongest and lightest bond that will never let go in any conditions. With that said, 3M 77 spray adhesive is a temporary contact spray adhesive; it even states that on the can. I use it for mounting sandpaper to sanding boards and thing like that, when I wish to remove the sandpaper I just warm it up with a heat gun or hair dryer and peel it right off. Something to keep in mind is the best doesn't always mean the fastest when it comes to building something. Anyway IMO the best and lightest bond is an epoxy bond and the use of vacuum, second best is a gorilla glue bond and the use of vacuum, and the last and still good is a 3M 30-NF contact adhesive bond, It will not let go with heat like 3M 77, you can roll it on, brush it on or spray it on, allow to flash and your ready to stick things together...
