Couldn't hurt. You don't need much.

I use it on my boat trailer light connector(s) and tractor electrical system. Both live outdoors 24/7.

I use it on my four classic cars especially since they don't see many miles and just sitting isn't great for electrical connections, never thought about using it on detector connections but I'd say go for it. Use sparingly.

I would not hesitate to use it but in moderation. Always use it on my trailer hookup. I have used on my ML Explorer, but my CTX 3030 has the WM 10 so no need.

Only problem I can think of is that it collects dust. It does prevent corrosion.

I use it all my battery terminals, especially my Game Camera's, out in the weather all the times. An remember in the old years you had to bump the back end of the Flashlights to get them to come on. No problems for that either. But, I have never put any of my Detectors yet tho... I would'n think it would hurt it

I too have seen globs of it on vehicle battery terminals in order to prevent corrosion

"Since dielectric grease is a silicone grease, it should not be used on silicone-based rubbers or plastics, as it will break them down over time. The grease does not conduct electricity, so it shouldn't be applied directly to the mating surfaces (pins and sockets) of an electrical connection."

yeah.... i am not 100% on this... this is just what the internet keeps saying.

Personally... i use 100% PURE silicone without problems for eons.

For the last few years i have incorporated the spray.

I have wondered if dielectric grease conducts electric current too. Guess I'll set ohms on a meter & see if get any reading.
Main comment to this thread is when I worked around Florida Power & Light the linemen would use it on the ends that plugged into the transformers of residential underground systems. I think the boots were rubber so grease made things slide instead of the friction of rubber on metal. The repair splices underground got some too but those boots didn't look like same material as transformer boots.

Dielectric grease does not conduct electricity though it will keep a connection from corrosion if in contact with moisture. I just studied all this because of my boat battery. Same with white lithium but it is for moving parts.
Silicone spray as stated is a good choice if used frequently.

Any grease will attract and retain dirt, sand and dust. So if you're changing coils often, I'd suggest running it without any grease. Otherwise, any food/scuba grade silicone (I use Trident brand) will work perfectly. Make sure to degrease occasionally to prevent abrasive buildups… Something like CRC QD Contact or Electronic Cleaner will wash it right off without any harm to plated contacts.
