We have a two year old Intex 12x24 oval AG. The top surfaces of the ring have turned brown and this evening it cracked open. We are probably on the verge of a collapse. One thought we had is to use some type of expanding foam in it. It would take alot of it. What can I use to recondition the vinyl? Last winter we left it up and it appeared to work out OK. I had planned on closing it this weekend. It is a salt pool and we rarely have to do much to it. I live in Mid-Michigan

Thanks for any suggestions
