## 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.
