Fred, I don't recall what the table leg looks like on the 25 but the one on my previous 22 was getting rusty and wasn't looking so good. I just took some 400 sandpaper to it and the surface rust came off pretty easy. Then I hit it with some wax and it looked pretty good again. You might want to try just sanding it down.
Fred, we have a replacement table leg, and it is a whole lot sturdier than the original, but as I think you observed, it was starting to corrode. Not sure of brand, we actually bought it from LUSR.
