Superficial rust

[boris]

Hi
Just bought my first scoot 1985 px 125 . 2 owners from new and seems in very good condition except for some surface rust below , foot pan is ok no rust appearing . Can you recommend what is the best way forward to prevent further rusting please?

I rub back to good shiny metal, apply a rust killer( I use jenolight, free from work) then spray with zinc rich primer, then ordinary primer and top coat
