Would this work in spark plug boots?

[The Artillerist]

Don’t laugh. I use MB dielectric grease on my MB boots.

A complete set of coils and plugs for one of my V-12 cars is about $3,000.

Is this the v12 you have?

A driven — as they should be — V12 with 300k on.

The Autozone used to give away those packs.

They actually were 99 cents, 20 years ago when I worked there. Though I did give quite a few away to good customers (read: nice people).

They used to run metrics on us that tracked how many we sold with related products. Brake lube with brake parts, antiseize with plugs, etc.

I was a frequent customer. At the time I owned 4 vehicles and was restoring a 1967 Chevelle SS 396. They had a well stocked bolt bin…

Pure profit item, no warranty, etc.

It is not pretty much identical. You are referencing a topic about silicone grease vs dielectric (which usually IS silicone grease), while Sil-Glyde is NOT silicone grease. It is castor oil based grease with some silicone in it. Big difference.

They use very deceptive marketing to sell a cheaper to make, inferior product for most uses except certain brake seal rubber which is not compatible with real silicone grease. Check out the material safety data sheet page 2 and notice "castor oil" 30-60%. https://media.napaonline.com/is/content/GenuinePartsCompany/175470532pdf

Only silicone grease should be used on (in) spark plug boots.

since refined castor oil is a dielectric and the purpose of lubricating sparkplug boots is to keep the rubber from sticking to the plug and keeping moisture out of the boot, seems sil glyde will work fine. works for me. also, battery terminals dont need dielectric grease. no matter how tight you get the terminals, if greased, there will be a layer of grease between the contacts. the purpose of greasing contacts is to block moisture and gases from corroding the terminals. spraying battery terminal oil/grease over the top of connected terminals makes more sense.

I have a tube of that juice and have used it as a boot "seal" for plug wires. @50k, they came of just fine. Do not get any on the connection of the plug to wire, but that is a general rule, other than dedicated a product like OXGard. Generally i do not put anthing in the boot, just on the ceramic portion of the plug.

like @kschachn said, you are just trying to lube the boot for later removal.

NO, it does not work fine, because the service life is terrible.

It's just a terrible choice if you don't have rubber that is incompatible with silicone grease.
