I have the Shine on Package by Surf City Garage, i haven't used it yet though. I have used the Clearly better glass cleaner and the road trip grime destroyer, after using the grime destroyer i could not find a dot of tar on my car. Also, the Clearly Better glass cleaner is the best i've ever used before. I have a long list of their products, haven't used them yet, but i am very impressed so far with their products.
