I have done a few mods to a PCB with 36 gauge mod wire. Obviously this wire is so thin that it only takes a few bends back and forth to break it. What is the best way to secure this in place on the PCB? I have tried super glue but that makes a mess because it flows too easily.

I use wire-wrap wire to fix broken tracks, or to modify boards. It's very thin, and easy to solder because of the silver coating. It breaks easily so some sort of glue to hold the wires in place is advisable, I just use masking tape, sometimes.
If you mean solid edge plating (rather than castellations) then it's certainly possible, but you will have to ask your PCB house if they can do it. As far as I am aware it's not too hard to do, it's just not such a common requirement (good for EMC behaviour).
One of the few prototyping companies that offers this option regularly is PCBWay.

At work I use Dow Corning 3145 RTV silicone adhesive for this very purpose. We also use it to secure flex cables in their connectors, secure right-angle parts such as capacitors to the board surface, fill small gaps to make the product waterproof, electrical component insulation, and so on. It is chemical-resistant, water-resistant, corrosion-resistant, non-conductive, and sticks to just about anything. There are many different uses for it, and in my opinion it is absolutely indispensable.
And to prevent this from being a specific product plug (I am not affiliated with the company in any way, I just like the product), I will say that just about any silicone adhesive designed for printed circuit board use will probably work great in this sort of application.
