I am assembling a Lanier SeaBird that almost the entire thing is plastic. It came with a very small bottle of what they have labeled aero-cement. When one applies it to a surface it seems to make the surface soft so that when you put the other piece on it, it kinda welds the two together. Problem is: if you leave the cap off the liquid evaporates very quickly and now I don't have enough left to finish the project. Any ideas what this is and where I might buy some more. It says it contains Ketones, what ever that is.
