The only Wolfgang product I have tried so far is the Deep Gloss Spritz Sealant. I loved how easy it was to use and really felt that it was a quality product. After using only this product from the Wolfgang line, I know that Wolfgang offers a great line of products and will not disappoint. One day, I'd love to have the entire Wolfgang line up if possible because there's just something about the brand that attracts me...maybe it's the idea of putting "German" products on my German car.
I am genuinely interested in the Deep Gloss Liquid Seal though. I can't imagine how excited I would be if I won it.
Good luck to everyone and thanks Autogeek!
