Give it a go and see what happens then let us know the results - I'm sure others would be interested in knowing how well (if at all) this works. If it did work, I could see it making putting in feeders much much easier.
I bought some about 7 months ago and wouldn't be without it. It does require following the instructions, which means you let it set up for 24 hours. I cover my liquid solder joins with JB weld which both gives substantial strength and also creates a non conductive covering.
Here is where I used it to make a good connection on some tiny wires, a home made working signal:
I covered the liquid solder with a coat of JB weld epoxy.
