Straightening bent rims

not needed with a rubber dead blow. as long as the surface is clean you will 
do no damage to the wheel.

but dead blow hammers dont rebound. thats the idea behind the 'dead' part.

just as an example, i straightened a snowflake for Foxx at cincy this year. 
even using rons dead blow (less weight than mine) it only took a few good 
hits. vw rims (teardrops, snowflakes, etc) are *much* easier to straighten 
than steel wheels. they are softer, and easily bent straight with a dead 
blow. there are some alloy wheels that are harder to straighten. the rieger 
wheels are a funky spun aluminum that has high flexibility / yield strength 
and they just keep bouncing back to their bent shape. to overcome the yield 
it takes some serious wailing, but they do in fact straighten.

side note - you want the heaviest dead blow possible, with a narrow impact 
surface if possible (~2" diameter works pretty good). also, it actually 
helps if the tire is mounted on the rim, as it adds more weight to dampen 
out the impacts.
