anyone know anything about polar pools? We have decided to chuck the ruined above ground pool and build an inground at the end of this summer. My husband, four brothers and four brothers-in-law are super duper handy and can do this! He is interested in polar pools because they have resin walls. I have looked through several posts to see what everyone else is doing and have noticed that most pools have steel walls. Husband is nervous about steel because of eventual rusting. Thoughts?
