What is a Rougaroo? A Rougarou is an ancient werewolf from Cajun folklore that lurks in the night. It was meant to be a cautionary tale to young children who didnt behave. said Bowen, regarding the inspiration for his new brand. In that same tradition, we bring the monster out in our Rougaroo products to provide car buffs with the ultimate car care wash & wax product. The cautionary tale here is the environment, and how were helping is by putting out a product that leaves zero impact, but still gives you the ultimate shine.
