I'm new to this site.
I'm torn between the two, Polymer and Steel? One company (very large company here 160 pools a year) says Polymer, because it keeps in the heat and Steel rusts. Another company (One man owner, he's on site, does 30 pools a year) likes to use good old reliable steel, but will do Polymer if I choose. I feel that the one company that wants us to use Polymer is just trying to sell their "stock", and I feel in my gut I should stick to good old steel. Can anyone give me some good advise/review on ether product?
