Yep. I didn't know it was now made by someone else. Also look at McMaster-Carr.
You might get a better price.

I've used Dow Corning #4 electrical grease for a couple of decades. It
really helps preventing corrosion and reduces heating of contacts. You
can also get it from Aklands Grainger.

Subject: RE: cleaning up edge connectors
Once the corrosion is removed I recommend using DC-4 on the
connections. It will protect the surfaces and keep great electrical
connections. It is a silicon grease that is non-conductive but keeps
the surface clean and improves metal to metal electrical contact. It
doesn't allow oxides to build at the contact surfaces.
It has measurable improvements of even gold on gold. I've used it on
solder to solder as well other dissimilar metals with good results.
I've used it on high current connections to reduce resistive heating up
to 1000 amperes.
Dwight,
Is this what you are talking about:
