    My 1997 Saturn SC2's hood is rusting from underneath. I guess it's
    been happening for a while, because there are a few spots where the
    top surface is bubbled up. Is there anything I can do to prevent it
    from getting worse, and can I replace the hood myself? Where would I
    get a replacement hood and do they come in colors or would I have to
    paint it to match?

    Thanks to anyone who can help me come up with a reasonable solution to
    this problem.

    Try this stuff or one of the similar formulations of rust reformers
    Permatex 81849 - Permatex Rust Treatment

    Loctite Extend

    Degrease the surface and throughly dry. Remove any loose flaking rust and
    then spray or brush on the compound (mind the ambient temperature). Should
    take two coats and the compound changes from a milky white to a black
    wherever there was rust. This will seal and stabilize the rusted area. Can
    be left as is or painted over following drying period.

    Hope this helps

    If the hood really is rusting through from the underside then there is
    nothing that will save it economically. Inner fenders, shock and strut
    towers and the undersides of hoods can collect salt if not washed regularly.

    If the rust is from water that has worked under the paint from rock chips
    commonly found near the front edge, then the rust treatments Oppie suggest
    can help but the entire hood will require repainting. There are clear and
    colored coatings such as 'gravel guard' that are often applied to the front
    edge of the hood and lower rocker panels and other areas of metal that are
    exposed to gravel chipping.

    The best and most economical repair will be to obtain a replacement hood
    from a 'do it yourself' auto wrecker. It is a simple job and you can
    practice when you remove the replacement hood. Look for one the same color
    as your car and no paint will be required. IIRC I paid <$15 for the last
    one I purchased. While you are at it you can get other parts like the cowl
    screen and wiper trim and blades and inner fenders that are probably better
    than the ones on your car. If you are more ambitious then take the plug
    wires, coil packs, alternator and starter and maybe the headlights. This
    will guarantee that yours will never need replacement as 'nothing with a
    spare ever breaks'.

    Good luck YMMV

    I just wanted to drop you both a quick thank-you. I will research
    both of these solutions. It is definitely bubbling through from the
    underside, rather than from a chip. I noticed the bubbling a long
    time ago. It didn't appear to be rust at the time, and I assumed some
    caustic chemical had dripped onto the hood somewhere causing it. By
    the time I thought to check the underside, the rust under there was
    pretty bad and now there is some more bubbling.

    I've never heard of a do it yourself auto wrecker, but that seems like
    an interesting solution and I'll look into it... Will report back!

    Thanks Oppie and Private!

    Sounds like a replacement hood will be your best option. This is where we
    wish that the hoods were plastic and not steel. A new one is ~$375. plus
    the cost of paint which can be expensive from a body shop. If you shop
    carefully you should be able to find a good used one that is the right
    color. Normal full service auto wreckers try to get 1/2 of new price but
    YMMV. I suggest that you do not tell them what color you need until after
    they quote a price.

    Self serve auto wreckers are very popular here and are a good source of
    bargain parts. Look for names like 'Pick Your Part' or 'Pick-N-Pull'
    If you give them your Email address they will send you a notice when they
    are having a half price day. 1/2 off days are a great time to get a new set
    of rims for your good winter tires, the complete tire and rim will be less
    than the regular cost of mounting and there are often some very good tires
    if you get there early. You will be lucky to get a full set of 4 but good
    pairs are quite common. Wear out your worst tires in the summer and mount
    new winter tires in the fall then remove them in the spring to save the

    The current throw away society has resulted in cars going to the wreckers
    that seem to have nothing wrong with them and would certainly have been
    repaired in the past. Many have far less mileage than the cars that are
    continuing to give me great service and which I expect to get much more

    Good luck YMMV

    I picked up a 1996 SL hood that was in excellent condition and matched the
    color of the vehicle for $50 at a local U-Pull-It salvage yard.

    Was the hood rusting underneath the sound insulation mat ? ( My daugther
    has a 97 SC2 and I'm wondering if I should pull the mat loose to check ?

    Yeah, I would check that! We kind of let it sit a lot, it's our
    second car, so I'm guessing maybe condensation built up on top of the
    insulation, that normally (hopefully) would have periodically gotten
    evaporated by the heat of the engine.

    I definitely have to check out these self-serve salvage yards.
