## Questions & Answers

**Q: Can i apply it to automatic window mechanism ?**
A: I've don it, worked great.

**Q: Would this do good to seal a usb port with a usb cord plugged in?**
A: Not sure why you need to seal a USB PORT but I see no reason it wouldnt keep it waterproofed.

**Q: Is this stuff good for polyureathane bushings**
A: Yes it is good for polyurethane bushings.....the lube they sell for the bushings is essentially rebranded dielectric grease too.

**Q: Has anyone tried this on fishing reel components?  Is it light enough?**
A: Definitely! I've been using it from 15 yrs or more... The main purpose, to seal the reel and protect screws from salt; for those that are not stainless I fill the hole with the grease to the top well, every where there is a screw head facing out. And all around the edge and bound surface of the gear cover, anywhere water can sip in! And in the gears, but I would mix it with other type to soften a bit for smooth reeling experience.
