Gary, I'm confused. They don't look to be the same product. One is for electrical connections, the other for brake calipers. Are you sure they are the same?
thanks.
Dielectric Tune-Up Grease is a silicone dielectric compound whose dielectric and lubricitous properties facilitate and improve tune-ups. The compound prevents voltage leakage around any electrical connector thereby insuring a strong spark in high energy automotive ignition systems.
The compound is also an excellent lubricant on rubber, plastic and ceramic surfaces and it also has good high temperature properties, thus preventing fusing of spark plug boots to the spark plug. It will make installation of the boots easier."
So I guess you can call it whatever you want. It's still a silicone product and can be used for electrical connections as well as a high temp lubricant for rubber spark plug boots. I use it on all my electrical connections as well as lubricating the brake pad pins and caliper sliders.
It's a handy compound that should be in everyone's tool box.
