We have been given a pool from my parents that is probably nearing 20 years old. From information I have been provided, I believe the pool to be manufactured by Seaspray and to be a High Sierra or Desert Shadow. Similar to many cases, we took down the pool to take to assemble at our house and the bottom track/rails were rusted. We are now needing to replace them on the 18x33 oval pool. Any help is appreciated.
