I've never had to lubricate any nuts on any basses I've owned before, but I recently purchased a guitar that may need a little help, as some of the string are a little sticky up there. I know guitar shops carry a product specifically for this, but I'm not making that drive today. I will however be at Home Depot later, and I'm wondering what these nut lubes are made of? Can I get the same thing by another name at Home Depot? Are they silicone based?
