Grease for Trailer Connectors???

My trailer/truck has a flat 4 connector and I am having trouble with corrosion and hence bad electrical connections. Is there any grease that I could coat the prongs with to inhibit this?

I've used this on mine and it does help: https://www.amazon.com/Permatex-2205.../dp/B000AL8VD2

There are lots of nice watertight 7 pin round connectors available, but in 4 pin the best I've seen are ones that have a cap to seal out water when not in use.....

Thanks Carbide

I'll try some of that. I think my truck connector had a cap, but it is gone. The connector on the truck is hard wired into the Toyota magic black box, so I hate to splice in a new one. Splices are trouble too.

One problem with using a grease especially if you don't have a good cover is that the grease will hold dirt. It's relatively easy to wipe off of the pins but grease and dirt down in the sockets can be a real pain to deal with.
