    What gauge sheet metal do you use. Where do you buY it from?
    Do you find that the gauge sheet metal varies a lot accross car years, or even car manufacturers?
    The local steel place around here sells 18 gauge. Thats the thinest that they sell.

    18 gauge is fine for most American 1950s-1960s cars. I don't know about '30s-'40s cars. You would not want to go thinner. I've used 20-gauge (thinner) for small areas but that was for convenience. All my patch panels and such are 18-gauge.

    thats usually it, unless you want something a little more pliable for complex shapes and such.

    18 ga works fine, and there are various types you can get (depends on your supplier) AK steel (aluminum killed) is easier to shape, cold rolled is nice and clean, pickled and oiled is also nice and clean to work with. Just depends on how much shaping you want to do. There's lots of good sheet metal books out to help you from the start to more advanced projects.

    I think a lot of Model A stuff was 19 gauge. Would not swear to it, though. It sure was good steel though.

    I measured the metal on a few old cars, floors and inner structures tend to be around 18 gage, outer panels are more like 21 gage.

    Measure the gauge on your vehicle and use that gauge if possible. My pickup is 16 gauge and that is what I used.

    16 ga. on the bed, most likely 19 ga. everywhere else.
