I bought an 18x52 Intex Ultra last fall to replace the blue Intex we had for 5yrs. Long story, but I ended up having to locate/buy all the horizontals and upright poles. I have the brand new T bars(only part of frame included in the new in-the-box pool that I was assured was complete) Because the posts I needed were interchangeable with the 16x48,20x48 and the 20x52 , I decided to buy a 2yr old 16x48 pool for parts and ordered the 2 horizonals and 2 verticals I still needed from Intex. The used frame is in pretty good condition with superficial scratches/abrasions on the powder coat and some tiny chips with rust. The inside posts are not powder coated and I see a fine film of rust. Is there any reason I shouldn't pull a piece of sponge saturated with rust converter through all 18 Ts and 36 posts?
