Default Recommendations for treating galvanized metal with rust?

So I'm in the process of replacing my rusty inner rockers and I have some of the galvanized areas (outter rocker and rear torque box) that have some surface rust on them. The rust in some places is quite light, but heavy in other areas, like the rear torque box. None of it is through the metal.

What is everyone's thoughts about treating these rust areas? Should I remove all of the surface rust and the galvanized coating down to the bare metal and treat with an epoxy primer? Or should I try to maintain the protection of the galvanized coating and just treat with a rust converter and then POR 15?

This is a tough one without actually seeing it.

I think your choices are to spray with zinc rich primer or spray it with a rust preventative spray like Rust Check.

I like to remove the rust and galvanized coating in the damaged areas and cover with epoxy primer. My personal opinion: Epoxy Primer is much better than a Galvanized coating

This IMO is comparing apples to monkeys!

Zinc coating protects steel by galvanic sacrificial action. This is an eletromotive action not a coating like paint. The magnesium rod in your water heater works in a similar manner.
