Doesn’t Stain. The concept for this high-tech formula was improvised by Marines, during Operation Desert Storm, who lubed up with actual military-issue “CLP” (cleans, lubricated, protects) in the sands of the Kuwait battlefields. Gun Oil Silicone Lubricant combines Dimethicon, the highest medical grade silicone, with Vitamin E and Aloe Vera. This unique hypoallergenic formula provides a long-lasting glide while protecting and moisturising the skin. Gun Oil actually contains no oil, so it is perfectly safe for use.
