As long as you don't power the track when it is wet, I don't think you should have an issue with either glue or matte medium.
I use "Dollar Store" alcohol for my wet water, as it is already at 50% or so. I mix my glue so it is like cream - maybe 50-50 with distilled water (from the dehumidifier in summer). No problems. This is also the method used by 90% of the guys at the club, and I have not heard of any electrical issues once everything is dry and solid.
If that is a concern, you could either solder the track sections at the joiners, and then cut expansion or electrical breaks after the fact, or solder jumpers between the sections. If you run a bus wire though, and have feeders for each section of track, jumpers and soldering are both redundant.
