If you're buying body panels to repair a damaged or rusted out area of your vehicle, there's a good chance you're going to need the right tools to help with the repair.  Replacing a floor pan or cowl section - check out the spotweld cutters and rotobroach kits.  Replacing a wheel arch - check out the metal sheers and flanger. Oh, and don't forget the stick lubricant to help extend the life of your drill bits and spotweld cutters.
