Dielectric grease use or not use

Dielectric grease use or not use
I have used in abundantly on all my low voltage connectors including the ECU and all other computer components, after reading the following.
"" Dielectric greases, and virtually all from other manufacturers, both improve insulation and preserve electrical connections. They do this by sealing contaminants, moisture, and air out of connections. They also seal insulators, keeping moisture and contaminants out of insulation.""
I used to have a significant number of electrical gremlins after hard tropical rains in South Florida. Haven't had then since.
Now, I read that there are opinions that dielectric grease might cause problems in the future.
Did I do right by my CAT using this grease?

Dielectric grease should be used on the outside of connectors,
not within the connector cavity.
For example, packing the seams and cable entry.
If you want something inside and are careful, then you can use
conductive grease which is not an insulator. You have to
be careful because you do not want to bridge adjacent sets
of contacts.

I been told that some very critical electrical connections where it is important that the connection carry full current. To use dielectric.
I have read an explaination that points out that the connection is not insulated by the grease. That there is enough contact between the metal parts to carry the current. The dielectric grease protects the metal from moisture and atmospheric elements, but does not insulate the electrical connecton itself.
I would have thought have multiple circuits and connections in one plug, and the plug is not fully insulated where you put the conductive grease, you might have a chance of a short-circuits.

Do not use dielectric grease on the ECU connectors!!!
Use this:
It's called Nyogel 760g and it is specifically designed for ECU and other electrical connectors. Ford packages it as Motorcraft XG12 but Masserati just leaves its original name on the tube they sell. Its designed for conductive surfaces. Protects against water corrosion, which was the problem I had twice with my 95 leaking drops of water straight into the ECU connectors. This product is used on ABS, airbag and multiple other connectors inside the cabin for it's water and salt water resistance , and can be used on the actual pins, unlike dielectric, which should never get on the actual pins and could reduce connectivity. . This stuff is NOT for engine connectors BTW.
