Ultraforce Gun Silicone Spray is a high-grade, low-viscosity lubricant that's suitable for use in gas, electric, and spring gel blasters. With multiple applications, it can form a protective barrier against weather, revive O-Rings, and lubricate plastic parts. Unlike mineral oils, silicone won't dry out over time and its low-viscosity enables it to cover any surface. For O-rings, use the dropper bottle to administer a few drops during upkeep or use the spray bottle in tight spaces or valve lubrication. Additionally, applying silicone to exposed metal shields it against corrosion, while its plastic lubrication is ideal for elements like tappet plates and blowback housings. Also, silicone oil won't seep into wood, so furniture is kept safe.
