## Questions & Answers

**Q: I have a new shotgun that is very hard to open for my wife. Will this help ?**
A: MY SUGGESTION IS GET YOUR WIFE A BB GUN

**Q: does this contain zink ?**
A: Yes

**Q: Is this suitable for assembling a non-synchronized dog-engagement manual transmission?**
A: Yes, I'd say that this stuff would work great for any metal to metal assembly. You must be working on an antique tractor transmission? Ben is right though, gear oil is what I'd use for gears that will be in an oil bath anyways.

**Q: Does this lubricant work on shotguns in winter outdoor temperatures? I'll be appling it to metal/metal sliding surfaces.**
A: Do a lot of shotgunning for ducks in Michigan's Upper Peninsula in sub-zero temps...we use CLP on EVERYTHING that can rust or needs lubing...we just make sure tool wipe off ALL of the access oil. Even though it looks/feels like there is no lube, it IS still there doing its job. This has worked for many different types of semi-auto shotguns in our group for many years now.
