    Best way to Remove oxidation from black hull

    Just picked up a 2004 12F, that spent its life on a floating dock. The sides of the black hull look grey from oxidation. Whats the best way remove it, I tried wax and it did nothing. Rubbing compound by hand worked better, but still not perfect and would take forever.

    Also the rub rails are faded, is a heat gun best on them? I thought I read that you can use paint thinner or lacquer thinner to bring the color back?

    I'd bet it's hard water buildup, rather than oxidation. Try some Ducky. If it's oxidation, you'll probably have to compound it.

    your right on the heat gun.
    thinners cant hurt, give it ago, just dont over do it just incase its not gel coat.
    rubbing compound with a rag it will work if your want a work out, maybe up the courseness of the compound.
    Idealy use a buff and compound.

    If its water/algae stains than use star brite hull cleaner, available at walmart or any boat supply store. contains a mild oxalic acid. spray it on wipe it down and hose it off. After the hull is thoroughly cleaned if the color isn't back than use a compound and wax afterwards

    Well, tried pretty much everything to get the gray off no luck so i did a quick compound. Came out much better, but I need to follow up I think with a finer compound then a wax.

    Wood cleaners for Cedar or Redwood have oxalic acid in them.

    ok, from the pictures that is not the type of stain that hull cleaner will remove, that is oxidation from the sun and can be removed with a good marine compound and wax. something else that works extremely well is Gel gloss for fiberglass tubs and sinks, home depot has it.

    Someone told me to try Penetrol, you can buy it at home depot. It's a paint additive and fiberglass conditioner. It didn't help with the oxidation on the hull, but did bring the black plastic pieces back to like new condition.
