Just a heads up to those that don't know. In life, you'll find that most everything is like real estate where the motto is location, location, location. In the world of chemistry it's application application, application. Using a car polish for a brass cleaner is not the correct application. In the formulation of Nu Finish, which I'll bet none here have a clue about, are Stoddard Solvent which is the actual cleaning agent that makes the brass clean. You might recognize Stoddard Solvent by the more common name of cleaning fluid.There's proprietary ceramic microspheres that are imparted on any surface it touches- read, like a dry silicone lubricant. It also has Oleic Diethanolamide which is a lubricant and a detergent. Most any cartridge depends on the brass grabbing the chamber walls during the pressure build, you have just deleted this most important function of the brass by using Nu Finish. Bolt thrust will be severe Yeah, I know, some have been using it for years and no issues. But some folks think if they can hit a 3 foot piece of paper at 100 yds accuracy is fabulous. Some think that just because the gun hasn't blown up yet it's fine. Eventually the rifle will start having head space issues from the bolt taking a beating. There's tons of rifles in the shops with headspace issues. So the gist of this post is, you now know better than to use a car polish for brass in a gun. It's your decision to use gun application products or use automotive application products on your guns. Yer on yer own.
