    I've used sodium silicate, but not for rust protection. I'll have to give that one a try.

    I purchased a jug of it to seal up a crack in the cylinder wall of an antique engine. Before adding the sodium silicate to the coolant the engine was running rough and blowing white smoke out the exhaust. When I poured about a cupful into the coolant the change was dramatic. Instantly, the smoke disappeared and the engine started running smoothly.

    I also use it in my electrolytic de-rusting vat. I don't know its purpose in this process, but the recipe I have calls for it.

    You can get sodium silicate from McMaster-Carr. If I remember correctly, it's only about $12-$13 per gallon.

    You can order it on line at:

    Type sodium silicate into the "Find" field. The click on the "+" that appears below.

    If you give it a try, I'd be interested in knowind how it turns out.

    Also check out your local pharmacy/drugstore as they often carry sodium silicate.

    An excellent preservative for tools and machines are:

    Camillia Oil - Japanese have used for centuries on swords and edged tools in high humidity environment.

    Boeshield T-9 - made by Boeing. Available as liquid or spray. Wonderful stuff
    If you want Square work, you cannot cut corners!
