Hello,

I am trying to fix up some body sheet metal that got
pretty banged up a long time ago, after which somebody
bashed it into more or less the right shape and put
tons of lead over it. I've removed the lead and
started trying to smooth the metal with hammer and
dolly and a stud welder, but it has gotten so many
creases and dents that it's gotten hardened like
spring steel, and seems to simple refuse to change
shape. (This is a fairly high-crown area in the roof,
right above the doors, and there are braces and stuff
behind it that make it hard to get access from
inside.)

Is there any way that I can anneal the metal or
otherwise make it easier to work? What would happen if
I just heated the whole area red-hot with a torch and
let it cool slowly?

Thanks,
