I do a fair amount of this type of cover "correction", Eugene.  The 
difficulty with the case on this style of cover is that it is fairly 
deep and because of the aluminum thickness and alloy, quite stiff.  I 
keep two foot long oak 2x4 and 4x4 "persuasion elements" in the corner 
to use with a graduated set of sledges, starting at 5 pounds and going 
up to 20.  Basically, you back up the bottom of the case on a piece of 
soft pine to allow for incremental movement, situate the 2x4 (or 4x4 
depending on the area of the depression) over the area to be 
straightened, and take a few whacks with the sledge.  Start with the 
lightest hammer and go easy.  Escalate as necessary.   :-)   Your eye 
and patience level will be your guide.  There are other ways of 
straightening it, including the use of threaded rod and large "washers" 
if there is a through-hole.  Ideally, the goal is to recreate the forces 
that created the bends, but in the opposite direction.  If you keep that 
in mind, you'll be okay.
