+3 on Por-15. I had swiss cheese for floor pans. I patched what I could and welded up any remaining holes. My welding skills are poor so it was not a water tight seal. I used some fiberglass with the POR-15 as well as seam sealer to fill in any holes. Worked great and is a rock hard finish. I have no door seals and routinely get water inside the car. No rust has come back.

I have also used Phosphoric acid on my engine block after hitting it with a wire wheel (see BigKev's blog) to neutralize the rust and recoated with engine paint. That motor is now outside under a tattered tarp and still rust free where I did the treatment.
