Hey there Grace! My AG has a resin top and has some kind of coating on the sides (not sure what it is called) so do you think that would still pose a problem with corrosion? I have already put some salt in my pool, but by no means as much as a SWG (Only 4 40# bags for 28,000 gal pool) and I hose the outside of my pool frequently to get rid of creepy crawlies!!
