The "pavement" on the racetrack is Wilton's sparkle black gel. It came out a little too shiny... didn't dry well, so if I had to do it again, I'd just "paint" the gel on. Making the fat tires was so much fun! I just had a ball creating this cake!
This cake was a lot fun because the advertisements were sooo creative! I didn't come up with the ideas, just copied them from the movie. Like below, it says "Leak Less - Adult Drip Pans" and "Retread Tire Deoderant" LOVE IT!
