CLR from Wal-mart about $5 removed the rust stains from my pool's diving
board.

I've heard muriatic acid, Rust Aid, or Barkeeper's Friend. I have the
same
problem, but haven't tried any of 'em yet.

You can try Starbrite's "Rust Stain Remover". I haven't tried it but
they
make
it for use on fiberglass.

should I use a polishing compound?

Thanks!
