Hi,

Just to add a little more information to this thread...

The CRC "Spray" Dielectric Grease is a total bust. It is not a 'spray' at all, it is more like an 'ooze". When you pull on the trigger, the grease oozes out the top nozzle the same way it would come out of a tube of the same grease after you squeeze the tube. So it comes out of the 'spray' can like toothpaste, not like any kind of spray at all. This means it will NOT shoot up into the tail gate door latching mechanism. This was a big disappointment as the cost was 9 dollars (USD) for a small can. Yeah it is grease, and is probably high quality, but it does not spray as expected so it cant really be used for the tail gate door latch unless it is taken off and greased like that, then replaced. The lithium grease really does spray out not ooze out. Maybe there is another type of spray dielectric grease (just clear silicone grease) on the market in a better type of can with a smaller tube too. The tube applicator part is like 1/4 inch in diameter, while the lithium grease tube part is only like 1/16 inch diameter, which makes a big difference when you go to try to grease something. I tried greasing the door hinges on my microwave oven and that was a bust too because the silicone grease applicator tube is too wide to fit into the narrow space where you can grease or oil the hinges. I had to use a toothpick to get some grease in there, and that doesnt work too well either.
Maybe i'll have to put together a custom made tube that will connect to the tube that is on the can now. Make the diameter very narrow, like 1/16 inch. The drawback here though is that the grease still wont flow into the joint, it will just hang out on the top like toothpaste. This kind of grease has to be 'spread' not 'sprayed' because it is too thick to flow like oil. The lithium grease does flow somewhat so it goes down into the joints without too much trouble.

Long story short (oh well, too late for that again) i am now officially tired of messing with this so the latch is now greased with the spray lithium grease. If it dries up i'll junk the car :-) :-)

Dielectric grease is for preventing corrosion on electrical connections before they are put together. Not for general lubrication.

Hi,

Yes but it is just silicone grease just like any other silicone grease. Maybe the brake grease has an extra additive, but i dont intend to use it for that :-)

Thanks.

Hello again,

Quick update...

I finally was able to obtain a somewhat decent oil can. Strange as that sounds, it's not easy finding a good one. This one isnt perfect but it does work, and shoots about 5 feet so it will shoot into latches and the like with no problem.
They had one at Ace Hardware. I had to order online then ship to store (no shipping) and then pick up at the store today. It was pretty hot out but i went anyway. The only disappointing part was it is not all metal, but part plastic. The body is plastic and the spout is steel. Not as good as the old one i used to have, but sufficient. The bottom is rounded though so it does not sit up stable, it rocks back and forth a little :-)

Did the kids huff the propellant out of your dielectric grease can or do they all just seep only??

Hi,

Not sure what you mean. The grease comes out just like a tube would when you squeeze it. I expected it to spray out.

Hi again,

Here is a link to the CRC 'spray' silicone grease:
https://www.amazon.com/CRC-05105-Technic ... JD49CSF6V3

Note again that it does not spray, it just gets pushed out of the nozzle just like as if you were squeezing a tube. The only difference is the nozzle is longer, but they could have just included a nozzle with a squeeze tube and it would be the same. The grease is also thick like regular wheel bearing grease, not runny at all, so it does not drip down into cracks that need lube.

The other silicone lubes are spray but they are just some sort of very light lubricant. They dry out too fast and need reapplication too many times to make them worth while.
There is another product though that comes in a bottle that is called "Silicone Oil", and that does not spray but i think it does drip down into cracks. I dont know if it is any good or how long it lasts in an application like a door lock or latch.

This thread cracks me up. :roll:

It says on the can "Waterproofs Electrical Contacts." That's why it's thick and not just a spray lubricant. But hey what do I know--I just use white lithium spray for latches like the rest of the uninformed masses. :mrgreen:

Hi,

Why does it crack you up?

Yes it is thick non flowing stuff, but so is the silicone brake grease. So it's almost the same thing.

I expected it to spray like the lithium grease i have.

I used spray lithium grease on the tail door latch now too :-)

It's funny because the grass is so much greener here than the other threads..

It might help lubricate the latch, if it is really dirty, to clean it with some meth yl alcohol.
