This is only lubricant endorsed by Rane. Used by big wig corporates like Boeing, Dolby, Honeywell, McIntosh. This is the legit synthetic solution used for moving surfaces and mechanims (faders, switches etc.). This 100% concentration droplet solution is recommended for re-lubrication after a full cleaning (which can be done with the Caig 5% spray or a light alcohol solution). These droplets give a smoother slide than the popular gun oil droplets and creates a bonding layer of wear-reducing, heat-resistant lubricant. To put it simply put this shit on your faders after you clean it and your faders will be smoother than when you first opened it.
