In my 40 of taking care of my cars, it seems I've tried most of the common tire dressings. A couple of years ago I tried Surf City Garage Beyond Black. It is definitely the best product I've ever used. I like the low luster natural look not the super gloosy wet look on my tires, and this stuff from Surf City really works, and it lasts for weeks. As it says in their promotional material "water-based, natural low shine clean finish, non greasy, won't attract dust, extreme protection from UV rays". I used it for a couple years on my previous vehicle and it did not cause any discoloration. I just ordered more to keep my Passport tires looking good. I am in no way associated with Surf ity Garage ... only sharing my experience and complete satisfaction with this product.
