I know! It looks terrible compared to soldering. But, there is a pretty large filler-metal 'drip'
hanging just under the area of the pin hole. That means it did get a bit runny..
In the center of the pin hole area, it got really fluid-like and that was enough for me.
I did not want all the filler-metal running off and under the tube, leaving only a
thin layer of filler on top of the pin hole.
My theory is, the pin hole is So small, that the chance of filler-metal actually entering
the hole is very low. So, I wanted a thick layer of filler on top of the hole,
but a layer that is well bonded to the copper. Just wish it had been pretty..
If it doesn't hold pressure, I still have the repair kit on standby..
