Its at least 50% graphene. Which is how many more times conductive than say, ANYthing else?
The answer, for practical purposes, is some number much less than 1, at least how you are using it.
Graphene is a 2D material. When made into sheets, it conducts very well in the direction of its lattice. When ground up or shredded into bulk like a powder, it is a poor conductor. You would be better off with regular old graphite.
If you like the Rislone (at least for mechanical and electrical), I suggest trying CorrosionX. Probably the only product I have used like this that actually works, and fully lives up to the claims and marketing. Not audio, so hopefully allowed. Check how positive the reviews are on Amazon. Almost nothing gets that good of reviews:

And if you fish, the reel oil they make is fantastic too.
