The Nature Conservancy and Brazilian ad agency Africa created the #NaoChoveNaoLavo (No Rain No Washing) campaign a month ago with social media campaign.
Today, they are promoting it with an ad featuring a guy who pulls into a car wash and is met by the young woman in a tight top and tiny shorts who slithers along the hood of his car while making slow, provocative cleaning motions.
She doesn't use any water, or remove any of the grime. Instead, we see at the end that she's written "No Rain No Washing" on the cars hood in dust.Source: http://great-ads.blogspot.com/
