I have a stain on my vinyl liner at the water line in my above ground pool. The stain is on the part of the pool that faces Southwest. A guy at the pool store told me to scrub it with an abrasive pad they sell at the pool store. I did that on Saturday and tonight I noticed that the finish appears to be scrubbed off below the water line. I didn't know what it was until I looked closely and saw scratches.

I did not tear the liner, but it is just a little bit rough in a couple of areas where the finish is gone. I hope I didn't do any damage, other than to the looks of the liner.

I hope someboy can advise me if this will result in the liner failing and if there is anything I can do to repair this.

Thanks!
