I'm not sure if you are missing the point or artfully dodging it. The point of my rant is to not use crappy containers. Ever. Crappy containers are the ones that require the use of a ziplock to protect the log. If you are going through a container selection process, and you start leaning toward "It'll be OK. I'll use a ziplock to keep the log dry", your container most likely fits firmly in the crappy column. If, during that same selection process, your thoughts are more along the lines of, "I could drive over this cache with an M-1 tank, then sink it to the bottom of the ocean, and the log will be fine, but I'll put it in a ziplock just in case", then you probably have a good cache container.
incase u havent noticed,,,most caches fit your crappy description. here we have had 80+ humidity, easily attained due point. even the local pros have damp stuff in water tight containers. I found 4 today in waterproof match containers, with water in them, no zip loc on the log...THERE IS NO PROBLEM WITH OVER PROTECTION.Unless you like to do a lot of maintenance.
