Steve, haven't been on in a while and just saw this.
I never drove on the short course return road at WoS in 2014 but the long course return road had many, many potholes filled with water.
Naturally, if there are any pin holes in the k-frame salt water can get in and start rusting from the inside out.
You might want to consider using something like this to seal the inside of the k-frame:

YES,,,,,I'm REALLY back to work on mine!
See you guys in Wilmington,
Gregg
