have slowly been restoring a modified windsurfer one design I got about 6 or so months back to like new condition. or as new as possible condition.

so far, I've replaced the mast track with a genuine one,
taken a knife to any jagged bits along the rails,
sanded the hull and rails with wet and dry,
glued and set the flaps and added mylar tape along the length,
sprayed he flaps with silicon pray
sanded back the centreboard.
board came with a new fin.

I recently picked up a second hand sail in very good condition and have tidied up the mast with new plugs so the entire setup is working like new.

only thing left to do is to remove the rust stains off the deck.

any ideas. I was thinking bleach? I've read ajax, gumption, clr.

wondering what people have used.
