I have inherited an Esther Williams above ground pool. It is around 10-12 years old. Everything on the pool was in great shape except for the bottom tracks (I ordered new ones) and I recently noticed dozens of pinhead sized holes near the bottom 6 inches of the aluminum wall. The previous owner had dirt up against the wall. I cannot afford to replace the wall. What would be the best way to approach repairing this?
Here is a link to a picture of the holes in the wall:
