Location: So. Cal | I don't know what country you are from, but generally, you can only purchase sheet metal in standard gauge sizes. .55mm is equivalent to .021" which is in between 23 and 24 gauge aluminum size. The typical steel sheet used on forwardlook cars is 19 gauge, or .042". More than double your aluminum thickness. So although, you could probably easily make a body out of that thin material, it wouldn't have much strength and would easily bend, maybe even from the wind resistance, depending on how fast it is going to go. What thickness you choose all depends on the size of the panel you are trying to create and the bends you want to put into it. I suggest that you get some different sizes of material and see what you can do with it. Generally, it is best to use the thickest size that you can make work. Thin sheet is really easy to work, but easy to bend if you push up against it too. Thick is hard to work, but will be much more durable and provide some amount of structural stiffness. Personally, I would shoot for at least 18 gauge aluminum, which is a little over 1mm in thickness. |

I need to make a body for an old dwarf car.
I am sorry but you can not use the terms "old" or "dwarf" anymore. They are too demeaning to the car. You must use the terms "age-challenged" and "size-challenged" as in
"I need to make a body for an age- and size-challenged car".
I trust you will not make such a horrible mistake again.
