You could take a nut or two off, maybe a plate and see if there is any crevice corrosion. If you see any sign of it there, you can sure there is some further down. Unfortunately, if you don't, there is no guarantee, but at least a good sign.
Your declarative statement of what you are and are not doing is not necessary. In fact, you may limit good advice. Whether you do it or not is always your decision, so why limit the learning?
