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 again?
Thanks in advance for your help.
