Hoppe's Lubricating Oil

The Hoppe's 1004 No. 9 Lubricating Oil is a long-lasting, perfectly refined lubricant with high viscosity, for all your firearms, fishing reels and other mechanisms. As time goes by, you'll begin to notice that this oil doesn't harden, gum, or smell awful in any way. This environmentally friendly formula comes in a pump-action spray bottle for easy application with a simple press of your finger.
