Hoppe's Gun Medic Quick Fix Lube utilizes the same technology used in jet propulsion engines for maximum and fast cleaning in a tiny drop. Gun Medic Lube coats your firearm in a micro-thin layer of lube to defend against corrosion, wear, and moisture. This technologically-advanced bio-based formula is highly concentrated, meaning you only need a little for a big job. This lubricant is cold/heat resistant to -65°F to 500°F for a fast clean in every environment. The easy-to-use 2-oz. bottle makes the job even faster.
