Let's start a parallel thread on the effect of coating a 14-gauge

Would this have any effect on velocity factor? If so, by how much?

The way it looks to me, the speed of propagation is pretty much the
inverse of the squareroot of the product of mu and epsilon for the
dielectric between conductors.
