As a lot of comments report, dielectric grease DOES NOT conduct electricity.
Please take the video down as a lot of people looking for advice on how to apply dielectric grease correctly run into this video.
avoid applying on electrode tip
Of course. Why would anyone even think of putting that stuff on the electrode tip?
Given that it 'conducts electricity really well' as Scotty tells, why not ?
Because the electrodes are inside the combustion chamber. Makes no sense to put there in the first place and would just get burned off in seconds anyway. Certainly would not help the spark either.
Does 'electrod tip' in the the instruction reference the metal piece that goes into the ignition coil ?
No, the electrodes form the spark gap and go into the combustion chamber.
"you need to learn the appropriate gap between the two electrodes on the end of each plug"

I see, the part that goes into ignition coil is called terminal.
Should dielectric grease be applied on the terminal ?
Most of it would be scraped off by the connector on the ignition wire or coil. What you want is to prevent moisture from getting in there so you mainly want it on the insulator to form a seal between the boot and ceramic part of the plug.
On my car the ignition cassette comes with the rubber spark plug boots already containing dielectric grease from the factory. Some will inevitably get onto the terminal during installation but as I said it winds up being scraped off by the connector. When changing plugs I just put more in the boots.

😆 Of course you don't put it on the tip. Spark plug tips are for making sparks inside the combustion chamber. You DON'T want ANYTHING in between the two electrodes except air. Dielectric grease is for making reliable electrical connections between two parts. (such as the spark plug wire, and spark plug).
Scotty introduces the dielectric grease as a grease that 'conducts electricity really well' - you can't disagree this is the exact opposite of what dielectric grease is.
Again, you're missing the point, which is that dielectric grease promotes a well conducting connection between two electrical parts. You can be sure Scotty understands this, and the general point of the video is correct. You should use grease the way he shows.
Are you a perfect robot? Do you pick apart people's words like this in real life conversation too?

Of course. Dielectric grease shields the conductors from corrosion. When I bought my old Pontiac, I had a heck of a time pulling the spark plug wires off the spark plugs, because someone had neglected to use the dielectric grease.

If you have wires :
If your engine has coil-on-plug, then here:
The top connector should already have a rubber gasket, making the grease unnecessary. But it wouldn't hurt anything if you still put some.
Don't be a nitpicker. The way Scotty shows is the correct way to use dielectric grease.
If in doubt, read the instructions on the product label.
And spare us the posts about Youtube comments in the future, please.
Thanks.
Filling the electric connector (including the wires) with dielectric grease as shown in the video is the correct way to apply dielectric grease ?
Yes it is. The whole point is to keep air and moisture away. Again, read the directions.
Scotty's hasn't been doing this for 50 years for nothing.
I went and did read the directions.
It says 'Coat the white ceramic insulator of the spark plug, avoid applying on electrode tip. Install boot onto plug and gently rotate the boot to distribute the grease.'
