There are many photos on the Super Car Workshop Facebook page that show the car just wiped down with wax and grease remover. If it is a bit "excessive" as you state, don't blame me blame Norwood. You can clearly see in the pictures a very heavy dose of white overspray on the underside of this original paint car we started with. Like fingerprints each car is a bit different. Why not just duplicate what you find on your car. That is always the best bet..BKH
