I am still a bit new at this... most of the solder connections on my JP machine are gooped with some kind of silicone. Is this a good practice to do with your solder joints? What does it accomplish besides preventing dirt on the solder?
I have a bad switch on the ball trough. Before I ordered a new one, I wanted to reflow the solder to make sure it was getting a good connection. I will have to remove the silicone though first.
