We had an intex pool and after one season of chlorine use the legs rusted so we wanted them and repainted them. Now 2 years later legs totally rusted and gave out. Seems to be rusted o my on bottom half of legs though. We purchased a new one and plan to use por15 to coat I side of pipes so my question is .....1. Has anyone done this already and what method did you use ? 2. Did you have any problems getting pipe to fit together? Thank you.
