Question for hrsdennis:
I like your idea about coating any exposed pool wall with tar -- are you suggesting just the outside of the wall?

I know that dirt can eat away at steel (even many-layered, coated steel), but wouldn't any standing water also do that? My thought is that if the liner has a leak and water is standing for any length of time between the liner and the pool wall, wouldn't that cause rusting out? And, if so, should we also coat the inside of the pool with tar? Seems a bit overkill, but I'd rather do preventive work on the front end, than deal with replacing pool walls prematurely due to rust.
