I just use di-electric grease on exposed connections. I gob it on and connect. Been doing that on 110 volt tank heaters for our stock tanks for years now with never a weather related issue.
I agree dielectric grease is the best way...
dielectric grease is nothing more than silicone grease, which can be purchased at napa under the sil-glide name
when crimping the connectors on the wire, dip the bare end of the wire in the grease before inserting and crimping... then add more grease before sliding the spade connector into its socket...
and its still easy to disconnect, unlike adhesive heat shrink which needs to be cut out and new connectors installed whenever it needs to be taken apart.
silicone/dielectric grease is the only true "waterproof" grease, so it wont wash out or become hygroscopic.
so as long as you can fill the cavity with it, it will displace the air and prevent moisture, which is the main source of a connection failing.
the silicone grease also helps to dissipate any heat that "over amping" the connection may cause, and will help to keep it from toasting itself to failure.
