Even though the whole tub was blown out with high pressure air to get all the sand out, it was still everywhere! I could only drive on the freeway a short distance before I had to get off and take side streets because I had huge puffs of dusty sand flying everywhere every time the Jeep would hit a bump in the road. By the time I got home I was covered by so much dust that I had to jump in the shower right away because I was a light shade of green. Most of the sand was up underneath the lip of the dash. in the heater box, the wiring, and in every little cubby hole.
