All the posts about Rusty walls have me looking at my pool. Our above ground is 2 years old and we have a bit of crushed stone around the base. I pulled some of the stones away and you can see it looks like the stone roughed up the paint which is bubbling a bit but there's no rust of any sort. I'm wondering if the bottom of the wall should be kept completely clear? Is this just asking for trouble later? Close up picture attached.
