Got some numbers (temperatures) for this one? Without digging out the data,
my impression is that baking the paint happens at a few hundred degrees F
and heat treating at much higher temperatures.

Were the tanks pressurized when baked, or did they blow up later?

The only thing you have to look out for with powder coating is if the
metal is heat treated. If the metal was heat treated the baking part of
the powder coating process can cause big problems with the integrity of
the metal. This happened on several occasions to people who had scuba
tanks powder coated, they blew up. If their's no heat treating involved
it's probably not a problem.
