The Mother's Back to Black is way too oily and runs down the side of your vehicle when it rains. I found that the product from Wizards Products (Black Renew) if far superior to the Mother's stuff. I use it mostly on the fender flares and steps on my Daily "Bubba Beater" 4 wheel drive work truck. Easy to apply and works great.
