DieElectric Grease question
I know nothing about this product.
What is it used for and is it of any benefit to me in my 68 Coupe?
I was thinking of using it on all my electrical connections as I reassemble the car. Is that a good idea or a bad idea.?
Does it help or hinder conductivity?
Can someone please enlighten me on the benefits or drawbacks of this product. The guy in the parts store didn't know anything about it.
Thank you,

Re: DieElectric Grease question (ksbunting)
Dielectric grease has three uses. As a lubricant (good in spark plug boots), as a thermal transfer (under the module on a HEI distributor), and as corrosion protection. As a corrosion protector it works well when not in direct contact with elements such as mating the two halves of the fuse box or inside of a electrical plug. It does not seem to hold up well on open connections like a ground point to the frame as it has a tendecy to wash off (but it is still better then nothing).

Pete,
Thanks for the info.
So if I understand correctly, it WOULD be good to use it on plugs and connectors like on the power window motors and any push-on connector plugs and as you said, on the fuse panel connectors??

i would not use D/E grease under the HEI module,use the white heat transfer compound used under transistors for heat transfer available at electronic parts stores. :chevy

BTW, di-electric grease on the battery posts prevent them from oxidicing.

Re: DieElectric Grease question (clem zahrobsky)
Clem,
That is an interesting comment! For years the ignition modules came with a little packet of clear di-electric grease for installation. Right from GM as well as the aftermarket. Was a lesson of some kind learned?
Or perhaps that little packet did not contain di-electric grease? From my shop manual:
"If a new module is to be installed, a package of silicone lubricant will be included with it. Spread the lubricant on the metal face of the module and on the distributor base where the module seats. This lubricant is important as it aids heat transfer for module cooling."
From the words on the package seen below (I assumed was di-electric grease, it is clear), "Contains silicone, keep away from painted surfaces." I am not challenging your advice ;) , simply a little confused at this point.

Re: DieElectric Grease question (paul79)
i have alway used the white compound because of working with TI ignition boxes in the good old days and the transistors were supplied with the white compound. i have no idea what the stuff GM supplied was,it could have been the same as the white compound without the color. the white compound is not as thick as the D/E grease. this change may be because this was discovered later that the white compound was better than the D/E grease. your guess is as good as mine on this. there are some EE on this site that could add to this disscussion. :chevy

Thanks Clem. It is so darn hot out I cannot even work in the garden much less drive my Corvette. Hopefully others will contribute to the discussion.
