DiElectric Grease versus ArmorAll

[HaroldCallahan]

For years I have used ArmorAll on the outside rubber trim around the windows on my vehicles with good results. Never used the dielectric grease recommended by GM. Thinking of starting now on my wife's new Yukon.

 

Is the dielectric grease really better than the Armor All ?

 

How much does it cost and where is the cheapest place to get it ?

 

I have a tube of the Permatex Dielectric Tuneup grease, is this equivalent to the GM part no 12345579 grease ?

Why would you use dielectric grease on the rubber and trim? Is it supposed to be safer?

[Musgofasta]

I've never heard of that. Maybe to moisturize the rubber and keep it from cracking. I thought armor-all did that too. Maybe it's not an oil product and safer for some reason.

2005 Yukon owner manual specifies Dielectric Silicone Grease, GM Part No. 12345579

 

Also, I think the 1988 GMC Manual specifies Dielectric grease as well. Also, I know that there sis omething called Krytox made by Dupont that is recommended by Corvette enthusiasts, but it is even more expensive than dielectric grease.

dielectric grease is silicon bases and helps keep the weatherstrip from drieing out and cracking, help stay flexable for better sealing, and keep from sticking to the door and ripping

Krytox is the best. Dielectric grease is a close second, and as mentioned, a bit cheaper. Never heard of using armorall.

You learn something new everyday. I guess it pays to read the owner's manual.

My father has some stuff called sil-glyde that Porsche recommends for use on the weather seals of his Carrera 4, but it is really messy to use. It is similiar to Krytox. I have always just gotten a can of silicon and sprayed it on a rag then wiped it on my seals. I like the Dupont stuff with teflon. If you use the silicon grease you have to really rub it in or else it will be sticky and dirt will stick to it like glue.

My wifes Honda minivan recommends dielectric grease for the weather strips on the sliding doors to eliminate squeaks and rattles...

 

It can be bought at AutoZone relatively cheap.

Dow Corning #4 Electrical Insulating Compound is what I use. Comes in a large tube. I applied it twice to the door seals in the 9 years I've owned my truck and they look like new. It's a silicone "grease" and both it and the Permatex product are equivalent to the GM stuff.

I've heard vaseline is same as dialectric grease, cheaper too.

I think I would rather pay more for dielectric grease than having to look a store clerk in the eye buying vaseling.

You could send your bodyguard or driver in to get it....
