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.

Try Ranex rust buster it should not effect the plastic !

thanks stroppo

+1 Stroppo's and PKenny's' comments.
Ranex is good...it's a phosphoric acid.
Septone make one too....it's got some oxalic acid as well as the phosphoric.

Worked a treat on my boat to remove rust stains around the stanchion bases and won't touch plastic.
Old toothbrush to work it into the deck..leave it a few minutes and repeat ..I've just been doing it on my epoxy board!!! Looking good so far.
If you use toothbrush, watch your eyes!

Also good for getting the coffee stains off your teeth.

I gave the rainex a go and it removed a lot of the rust but left a lot behind as well. I then scrubbed the deck with sugar soap as well. it is looking shiny and white now but I need to hit the rust more.

will try the septone next.

I think Stroppo said 'Ranex', not 'Rainex', in case you bought the wrong stuff.

Sending you a msg re Septone product I have available

Did you try lemon juice and salt?

alrighty,

I hooked up with Greg this morning and "borrowed" his pack of septone. seems like good stuff and has cleaned the board but hasn't removed the rust stains. They are beyond modern chemical warfare!

Mind you the board is now so white I need to put on sunnies to admire it.

I'll give the ranex one more go. Will make up a compac and apply that. (spelling?)

After that it's lemon juice time!

will take to the hull with some 1200grit wet and dry to finish that before applying some hullkote.

try a small area first, sanding polyethylene might make it furry...

I was probably lucky because I didn't give any thought to furring.

I started with 600grit and a block and hand sanded. that worked ok so I switched to the electric pad sander. last night I hand sanded with 1000 grit as a final run. no furring. as you can imagine that plastic sheen has gone.

I was reading some stuff last night on fixing deep scratches. they suggest a hot knife. have never tried it.

I found this site last night as well.

I gave the ranex one more go. Left it on for 3 or 4 hours this time and the rust is almost gone now.

Hope it goes faster!

thought I might mozy on down to this one.

guess I better start sailing in deep water and get used to running dead downwind in swell.

thanks mikey.

thinking a trip to bunnings may be in order now.

i'll give the clr, and lemon juice a go.

looking at the board this morning I have certainly removed a lot of the staining with what I've done so far. it is actually starting to look pretty good again.

You'd better get squeezing buddy ready for the WOD Nationals at RQ 27-29 November 2015. They will be run together with the Raceboards Nationals.

Is this official

go to bcf or bias boating and get some fiberglass hull cleaner make sure you mix with water in strong mixture apply it several times and leave it for 5 minutes each time this will remove rust stains
