The Walther Gun Care Pro oils and sprays were conceived for protection and care of hunting and sports shooting guns: not only they clean and lubrify, but they also create a protective film that will keep water away and protect the most important and sensitive parts of your guns from wear, rust and damage caused by aggressive foreign elements.
The Walther Gun Care Pro Expert oils and sprays were conceived to do exactly the same thing, but to service and defensive firearms. As such, they were tested, and are certified, to work at temperatures between -50°C/-58°F and +210°C/+410°F. The protective film they create doesn't smudge, is not sticky, will not retain fouling and will not attract dust or other elements.
