Epoxy primer over Rust converter

Can I put epoxy primer over rust converters like Por15 or Rust Encapsulator.

This is for the interior floors and trunk of my car, For the most part the floors and truck are in awesome shape with the exception of the drivers and passenger from pans that have some surface rust on them, no holes.

The resto of the paint is intact and looking good, I want to scrape out the seam sealer, sand and treat the rusted spots and scuff up the original paint and spray with an epoxy primer.

Do you forsee any problems with this or is there a better route to go?

Thanks
