I have metal handrails, painted white, that attach (underwater) to the steps in the pool that are peeling due to the prior imbalance in the water. I haven't yet located a source for paint suitable for metal submerged in swimming pools. Does anyone have any knowledge of such paint, or any suggestions? I can replace them with plastic handrails, but at the cost of $100, and the originals are only 1 season old. Thanks for any ideas.
