my treatment of the rust... shown below...

i think my process & product choice will work great as an end result. i am keeping the repair area concealed beneath the rubber trim.



product used: por15

here are pics of my repair:

used metal ready (applied with a hobby brush) to treat/clean the metal & rusted area:


used blue painters tape to mask & keep the area treated confined under existing rubber strip:


applied 2 coats of por15 (with hobby brush) to the rust and seam area for protection & elimination of existing rust:
