StewMac nut rescue powder for filling nut slots, SM2348

Don’t replace a nut just to fix one low slot — fill it instead. The StewMac Nut Rescue Powder (SM2348) is an easy, reliable way to stop string buzzes and bring worn nut slots back to proper height. It’s ideal for players and techs who want a clean repair without the cost or hassle of making a new nut.

Traditional fillers like bone dust or baking soda can be messy, hard to colour-match, and may leave the slot rough. Nut Rescue solves these problems with an ultra-fine, packable powder that blends naturally into the nut material. The special formula includes built-in lubrication so the string slides smoothly, improving tuning stability and overall playability.

Developed in Joe Glaser’s respected repair shop, this set includes three 5ml bottles — cream, white, and black — making it easy to match bone, ivory, Tusq, corian, ebony, or other materials. The included applicator lets you measure and apply the perfect amount every time.

How to use:
Clean the low slot, pack in a small amount of powder, add a drop of thin superglue, let it cure, and then recut the slot. Each bottle lasts a long time and delivers a strong, permanent repair that keeps vintage guitars original.

Features:

• Ultra-fine powder for clean, tidy repairs

• Built-in lubrication for smooth tuning

• Fast, durable, and permanent fix

• Helps preserve original nuts on vintage instruments

• Three colours for perfect matching
