Jack, I know that you’re not trying to start an argument and neither am I. We’re just sharing our personal experiences here.
I also did not want to pick you up on the salt water, but over a period even stainless steel will rust . That is why it is best to rinse the cockpit out or at least sponge it out after each salt water paddle
That depends on the particular stainless alloy. Some will rust, but there are some that are completely impervious to salt water. Of course, the more resistant alloys are more expensive, so lower resistance alloys are often found in kayaks. There may also be limitations to how these alloys can be employed. For example, I’ve seen lots of screws, carabiners and other hardware that don’t rust, but I haven’t seen any stainless steel skeg cables that are completely impervious to rust.
