One week after one lap the car is completely filthy. My daughter and I peeled away at the coating - it was fun for the first 15 minutes - well she could have kept peeling - she love it. I took the pressure washer and took the coating off very easily.
Here's how it looks:
I had it detailed just before I put on the coating and now it's just as clean as if it was just detailed. I used no soap or sponge!
here are the wheels before: (notice I started it a little before I snapped a picture)
after a few passes of the pressure washer
I left lots of the coating all over the ground. Notice the front wheels have the film removed. The rear still has it on - it was matte black from 5000 miles of brake dust!
