I found the wooden baseball bat method best myself as have some of my friends. Louisville Slugger.
Another method that actually is probably as good or better (leaves no void to invite rust) is to take a belt sander to them and just sand them off. Sounds rude but hey, it's a car. And it's your car.
If you want an investment, Enron stock is probably selling pretty low right now. And they're in the electric power business. When they're done throwing that industry to the greed lions, drinking water will be the only industry outside the NYSE. Stock up now and save.
Okay, now I know I'm getting out of control again.
Okay, I can't this edit: When electric power is finally deregulated, watch the promises of better service and lower prices be fulfilled.
