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?

In his book _Ferromagnetic Core Design & Application Handbook_
Doug DeMaw claimed to have put ferrite sleeves on a vhf dipole
which reduced its size without introducing significant loss.
He claimed to have cut the size of the dipole in half.
You'll have to do the same thing yourself if you want to know
whether or not he was right.

Yea, but isn't that the same thing as winding a helix to increase the
inductance per unit length to accomplish the same results. I don't
know if Doug was right, cause I have not done either. May try it.
