I arrived home yesterday to find my tire shine waiting for me, so I couldn't wait to try it out today! The Mustang was pretty dusty, so I gave it a good cleaning, used APC to thoroughly clean the tires, and applied the tire shine (using the less-shiny method Adam demonstrated).
I'm really happy with the results! I drove the car less than a half hour later and the tires were completely dry with no slinging at all. I did get some overspray on the wheels but it wiped off no problem and no dirt has stuck to those places that I could tell, or to the tires themselves. Impressive considering there's a lot of construction going on around here and plenty of dirt on the roads. I was especially happy with how easily the product filled in the ridges in my tires with hardly any effort (using a fresh block sponge).
