    repairing rusty gas tank

    I have an old dirt bike from when I was a kid and I want to get it running again for my kids. The gas tank has a good layer of rust and crud inside. Any tips for repairing this?

    I have used electrolysis on several old jerry cans with good effect - there are numerous methods for using it on the web.

    You'll also want to finish the job with a sealer - Kreem is one brand, IIRC, they are common for rebuilding motorcycle gas tanks.

    I've even seen tanks half filled with gravel and then rotated to remove rust and scale.

    It will be a slow process and patience is required...Good Luck!

    No advise on how to clean it but Red Kote will seal it well once it is clean.
    Have you ever seen a man eat so much fish?

    Did you ever get this fixed? I've had good results using distilled white vinegar. Make sure to neutralize it afterward. (I use baking soda for that.) It's a matter of opinion, but I wouldn't coat it - too much risk the coating can flake off, causing more problems than it solves.
