Electric conductive glue

Is it any good?
Is it strong or is it crap?
I just bought a SON coaxial cable junction box and adapter for the wiring on my new bios project. It requires some pretty accurate soldering by the looks of things. I have the kit but my soldering is usually lumpy and clumsy even with the work clamped.
In need to make some pretty fine and fiddly joints that will not only need to be good contacts but also be load bearing in the sense that they will hold a jack onto a cable and be good for multiple insertions and rough use.
Could electric conductive glue achieve this? Or will I need to rapidly improve my solder technique?
If glue is any good can anyone recommend a particular brand?

I’ve used these glues in restoring circuit boards on retro computers. TBH I’d be nervous on the load bearing side of it if the wires are subject to movement.
Do you use flux when you solder? This, a clean iron and the right temperature is the key to unlumpyness

Thanks Dave. Do you need flux even if the solder wire is supposed to have flux added?

I swear by it when doing fiddly work. I use it from a pen and it helps solder flow and not ball up

You swear by it
I’ll get a flux pen. Where do you apply it? To the solder wire, the work or both?

To the capacitor!

I flux both surfaces which the solder will be asked to adhere to. Must admit I’m still not the tidiest of solderers and invested in a bench vacuum desoldering station to make good my mistakes. My biggest mistake has always been not keeping the iron head spotlessly clean.

Guilty. How best to clean it if this is the case?

My method is to dip the tip in flux when hot and then rub the tip with fine wire wool - mind yer fingers

the iron may come with a bit of a compressed sponge pad. damped it, (it will expand), clean the tip on the wet pad. it is
not plastic foam it doesn't melt!

sponges are cellolose foam or alternatively may be fine brass wire =brass 'wool'.

Have you looked at Silver Loaded Epoxy?
It is claimed to have conductive properties and at the va level of a SON
it might work.

Thanks for the tips chaps.
I did the (for me) terribly fiddly soldering job and now have a very nifty wiring loom for the dynamo powered goodies on my Krampus and will do the Fargo some time soon.
