I start out in the spring on my red truck with two coats of the Wolfgang's sealant, then I use the
Souveran the rest of the summer (I'm waxing everytime I wash).
I've done as much as four to six coats of the
Souveran, and I have to say that after two or three, the difference is almost nil to none. Of course you might think there is a slight difference, but your mind is going to want to tell you that!
But on my red truck, I have no more favorite combo than these two.
