Towson, Md.-based DeWalt has signed an agreement with Richard Petty Motorsports to sponsor Marcos Ambrose, driver of the No. 9 Ford Fusion, for the 2011/2012 Nascar season.

The No. 9 car will now brandish the DeWalt logo, which will alternate between the hood and quarter-panel during each race of the 2011/2012 Sprint Cup season.
