rim lips

on stock steel rims i've used a blunt chisel and hammer to get that little curled lip back into semi-shape,
on A/M aluminum rims i like a rubber mallet

if you're looking to get them back to perfect...good luck
 
Use An Adjustable Wrench , you know the ones with the thumb slide , make it fit the lip of the rim and bend it back , its real simple and you can make them look much better ! , you will be able to notice they were bent , but it will look much better than the actual bend !
