Just don't let them go back and forth between the wheels and paint. AHHHHHHH.
My cousin, who is 11 now, when he was in preschool led the rest of the kids in washing the teachers car. LOL He kept telling them what to do and if the sponge touched the ground, he let that kid know how wrong they were. LOL

In every pic your daughter has her hand behind her back or to the side. whereas that boy is touching the car in every pic... You have taught her well... lol.... Kids are a blessing...
