Ultra-Pure Heavy Tuning Slide Lube is a safe, all-synthetic grease that is used to keep tuning slides in place. It is especially useful for loose tuning slides that tend to fall out over time. Very sticky stuff!
Usage info: Remove each slide and wipe off old grease with a paper towel. Apply a very small amount of fresh lube and push the slide back in. Wipe off any excess. Do this each week for best results.
