    Default Battery tray rust

    Leaking battery acid has eaten away paint on battery tray. Some surface corrosion has developed but nothing a wire wheel won't fix. Could someone please specify the exact products I need from Supercheap auto to neutralise the rust and protect into the future? (need to shop online and have delivered - no time to do it any other way).

    Hi there,
    Su'cheap over here in N.Z. used to sell 3M Rust Neutraliser, which is an excellent product, but have recently ceased stocking it. Hopefully you can get hold of some over in Aus. I've successfully used Septone engine enamel (from Su'cheap) as a finish coat.

    Cheer, Henry

    Best stuff is Zinga, a cold galvanising system. You can paint it.

    I usually pull the battery and tray out about every 18 months. wash the whole area with hot water and bi-carbonate of soda (neurtralises acid) two desert spoons in a bucket of hot water. I wire brush, deoxidine and paint with generic rust guard or similar. There are typically a few bubbles and some white poweder in the paint at 18 months.

    if you wire brush it that much you cant see any rust, isnt that good enough? (assuming it hasnt eaten through)
    The wrong oil is better than no oil at all.

    If you mix up a teaspoon of bi carb in a glass and slop it on and it doesn't fizz up, then there is no residual acid.

    ....or you could paint it with Zinga and it will never rust again, acid or no acid.
