MG Chemicals - 847-1P Carbon Conductive Assembly Paste, 1 Pint Jar

This is the best product to use for any type of electrical connections, I used it in the sockets of some old outdoor light fixtures, the sockets have the old copper threads and kept corroding due to both moisture and the contact of the aluminum base of the bulb to the copper threads in the sockets. The bulbs would fail and the bases would sometimes get stuck and break off in the socket. This paste solved that problem by making the transition between the copper to aluminum contact also keeping moisture out and the socket lubricated. Good for both high and low voltages. Note: a very little goes a long way, it is very black in color and greasy and can be messy if not careful, After I cleaned out the sockets with a rotary tool with a small wire wheel to remove the crusty corrosion I applied it with a Q-tip on the threads and dabbed a little bit on the tongue in each socket. Since then no more problems, the corrosion stopped and the bulbs and lights still work great.

It's nuts how many guys put dielectric grease between connection points, which acts like an insulator! THIS is what you need between connection points, then put dielectric grease on the outside of the finished connection to keep moisture away. Recommended.

The product is great. The packaging? I have read a few reviews where buyers have said their item was used and resealed. So although mine appeared that way, (see pics) the contents inside looked undisturbed or unused. The outer package was scotch taped closed and the jar had white tape oddly around the cap. I find it hard to believe that the manufacturer would package it that way. It's expensive stuff. If I thought there was any missing I would have returned it.

Just a tiny amount does the job in the radio gear I'm working on. Just enough to ensure a proper ground between these screwed together parts. I've verified with a multimeter that this stuff enables a good electrical connection. In the data sheet the manufacturer warns that this stuff can be very messy. They know what they're talking about. Use great care in application and handing the part after.

I just had great success by applying the tiniest little dab of this paste on the GPS antenna contacts of my Samsung Note 3.I put just a pinhead dab on each spring contact that touches a pad on the back cover. I did all of the contacts, not just the GPS contact (That's in the upper left corner, as you look at the back of the disassembled phone).I've got essentially the whole 1 ounces of grease left. I wish I could easily get a small dollop to all the other people who need it out there. This 1 ounce jar would fix thousands of phones!

Works great. A little goes a long way.

I have only used this for a short while so I can't speak to long term effectiveness.In the short term it makes conductive connections. They look well protected by this sticky black substance.

This didn't work at all for me. I needed it to conduct electricity within a plug-in connection at the back of my car's lighting control module. It didn't work at all. I'm not sure why.
