I don't use a lead hammer...I use a 1x2 inch piece of solid oak about 2 feet long (home depot). The oak leaves no marks on the aluminum knock off and the hammer you do use is away from the wheel and body, so no chance of a mistake. It's moron proof...almost! I've removed one wheel or another at least 20 times without an issue.
The other option is to flip the car on it's top, hook a chain to one of the "A" arms , and drag it to the gas station.
