For your "surface rust" I would abrade the area using media blasting (garnet), or wire wheel (crud thug?) or similar that will turn area into a bright metal finish. I'm not a fan of POR type products as their success rate is sketchy at best. Any rust left will still be prone to further rusting under the POR covering. While you have it apart, if it were me it would be media blasted and painted with SPI epoxy primer. Fix it right, fix it once.
X2 on that SPI approach. Take it to bare metal first.
