How did you paint/finish your gas tank? Options

[Tdskip]

I pulled the fuel tank out of the Fresno 914 because it sat for 20+ years, and I’m not sure if it was properly drain first or if the fuel just all evaporated. Seems like a bad idea to just dump gas in it so it’s at a radiator shop being tested and cleaned out.

That, however, leaves me without a fuel tank to get the car fired up and I happen to have one that was dipped but is unfinished. Since the tanks are identical and not stamped I can swap them out without the car sliding into the “non-numbers matching “category. Doesn’t really matter because it’s a bit of this and get to that car since I bought it as a roller anyway. Ha.

So-how do you guys like to finish and recommend repairing the fuel tank. It looks like the tanks were originally just painted and assembled into the car without any interior lining to the tank, correct? Do the same thing or do you recommend getting them finished differently?

Thanks!
