Sour Power is Dodo Juice's Gloss-Enhancing Shampoo with added premium carnauba wax to enhance gloss and add protection during the wash process. This shampoo won't strip wax or sealant already applied to your car and is actually a great way to maintain an existing wax coating or rejuvenate one that is starting to fail, why simply maintain the existing coating when you can keep topping it up every time you wash.
