I am new to the site but i fell in love with the Z several years ago and i am currently shopping for one. I am distressed to find out that they suffer so greatly from rust. I was wondering if anyone had developed fiberglass replacement pannels to solve this problem. it seems to me that it could at leaste handle, the seem, and drainige situation. I have read several post but no one it seems has speifically adressed the issue of replacing the metal with fiberglass. Anyone's feedback would be appreciated.
