  • Help...anyone have advice on rust stains??

    The "master boat builder" that owned my 25 cc before me had a thing for sheetrock screws. I would like these rust stains to disappear and David Copperfield is booked up. I have heard everything under the sun, but people in these forums seem to know what they are talking about.....thanks

      oxolic (sp?) acid....try those little plastic cans of blue jelly called 'FSR' - 'Fiberglass Stain Remover', or 'The Works' toilet bowl cleaner. Will pull them right out, just apply, let it sit for a few minutes and rinse before it dries.

            cheapest way is to buy oxalic acid, its a weak bleaching acid and is also an iron scavenger other than that try any of the boat care products ie davis fsr, rule fiberglass stain remover etc

                Carpetdiem-

                If those products that others have recommended dont work.....Take some wet/dry sandpaper on a block...around 1000grit and try to gently wetsand them out of the gelcoat. If the 1000 doesnt work, move down to 600. Just be careful not to sand through the gelcoat.

                    The absolute best is On&Off hull and deck cleaner. Not only will it take care of the rust it will make childs play out of any water stain

                    you can get it a most marine stores. Go ahead and sieze the day and get some

                      Mary Kate On/Off is an acid sold at most Boating stores. You may have to treat it several times to remove heavy rust stains.
