small dents can be pushed out by hand if you can get to the other side of the panel flav, dont push too hard or the dent will be an outtie <-- rather than an innie.
if theyre more like creases then it'd pay to use the right tools or get a paintless dent repair co. to do it.
But seriously, if you go to the autobody section at Walmart, you should be able to find a large suction cup with a handle on it. It's used to pull out dents. It actually works pretty well provided the dent hasn't stretched the metal.
There's no creases. I'm going to have to see what it takes to get to the other side of the panels. The suction cup thingy sounds cool and convenient... *off to find one on the web *.
edit:
Found these two
for $3.99
and
For $16.95
The second one looks like you need to put a screw in the metal though.
