So here is my problem... I have an 02 sedan and there is a lump on the driver's side floorboard that runs from behind the driver's seat all the way to the the driver's side passenger floorboard. The lump is facing upward. On the underside of the chassis I can see where it got bent. It seems to be the aftermath of someone running through a speedbump at a very fast speed (or something similar for that matter). I recently asked the shop I go to about this, and also went to a body shop and they both recommended that I just take a block of wood and hit it with a heavy (probably like 5-10 lbs) hammer. It seems to be strictly cosmetic and there appears to be no unibody repairs and all the VIN panels match, so I really doubt it was something serious... My question is, what is everybody's take on this method of "repair"?
