Review: Buy it, don't put it off! - Great price, good product. I use this for battery terminals, wiring harness plugs and any junction box or electrical connectors on my cars (light bulb sockets holders, for example). This keeps all contacts really good and clean and repels moisture which corrodes connectors and wiring - causing high resistance and electrical gremlins from poor conductivity. As it also lubricates wiring harness connectors (especially HT leads clipping on to spark plugs) you save yourself the hassle of fighting with seized connectors and frustration and expense of replacing anything that would have broken trying to get it apart. Cheap insurance really.
Review: A lot cheaper than specialized vacuum grease and does the work perfectly

## Questions & Answers

**Q: Can i use it for greasing the car brake caliper slide pins?**
A: This is not the right product for that. The silicone grease part, yes. The dielectric part, no. There is a silicone grease meant specifically for the slides on brake calipers. This is not it.

**Q: How thick is the grease? Would you say as thick as wheel bearing grease or maybe vasoline?**
A: Yes - very similar in viscosity to either vaseline or bearing grease.  I absolutely love this stuff, my boat mechanic had recommended a few years back to me and I keep tubes in the garage and on the boat.  Quality grease that is synthetic and won't react or break down insulation, great for crimp terminations and electrical joints in general - highly recommend

**Q: Would this be useful for electrical contacts in a marine environment?**
A: Useful yes, but not the best choice.  If you use Super Lube #21030, it will do just as well as #91003.  The difference between these two is their compatibility with certain plastics and rubbers.  Really though, the best product for you would be Super Lube #82003 or #82016 (those two are the same "stuff", one is 3 oz tube, the other is a little "bucket" of 400g).  Those are specifically designed to be used as connector gel.

**Q: Can this be used to grease e-bike hub motors?**
A: Dielectric Grease is protection from corrosion, Not a lubricant to speak of. I would say No to your application....but I could be wrong.
