Instrument Cluster plastic repair issue..

What about hot glue? I would expect it would do the job well.
Need to rebuild the posts a bit so I have something to hold to....in removing them, even being careful with my soldering iron, many of them mushroomed or blew out as the metal plate got hot as well. I could use some milliput, jb weld, or green stuff to make a new base post..
