Fiat 500 Rust

Bought a 1972 classic Fiat 500 a couple of years ago.

Stripped it down, got the whole car media blasted, and a coat of acid
etch primer on top, with the intention of putting another couple of
coats of build primer on before getting it painted.

Life being life, a family member got really ill and needed 24hr care for
the next couple of years. So the Fiat 500 project was left to sit in
the garage, in nothing but it's etch primer for a couple of years.

I'm now in a position to finish the project. I've had a look at the
bodywork, and the primer has lots of small rust spots all over. I done
quick trial sanding back to the metal, but I've noticed very feint small
black/grey dots which I presume are the remnants of the rust. How deep
will these little roots go? Should I treat the bare metal with Jenolite
before spraying the new etch prime, or should I have it media blasted

Thanks in advance for your help.
