We have an outdoor pool with a vinyl patterned liner which is about 4 years old. The area around the edge that sits out of the water is faded and looks dirty though cannot be cleaned up any. Are you able to add/ glue a pelmet on top of the existing liner to give it a bit of a face lift? The liner under the water is fine and still in great condition- so seems a shame to replace the whole thing when just a 30mm pelmet stuck on would improve its appearance 10 fold? Anyone know if this is a thing?
