Slide-O-Mix Trombone Slide Oil is the lubricant of choice for many internationally well known trombone players. 

Slide-O-Mix Light gives your slide a fantastic glide. It is a 2-component liquid lubricant, which adheres very well to the slide surface. There is no sticking or stopping of the slide.  

Slide-O-Mix Light has an even thinner gliding film used for "problem" slides -  more newer, tighter slides.
