I started with a hammer and a the edge of a small block of wood to get the edges moving, then moved to baseball bat. I used the wheel and tire as leverage for the bat. If you're worried about your paint, this isn't the best way to do it.
Recently, however, i got a good deal on a fender lip roller and went back over my original work with it. This tool works much better if you can find one. You can also supposedly use a heat gun on the lip to keep from killing the paint. I wasn't really worried about this on mine.
