Wax Waster
I`d still put some type of sign inside the car (same style as a handicap mirror hung tag) that clearly states "DO NOT WASH,NO TIRE SHINE" on there. Remember the valet/porter guys may not have easy access to work Order and may still give it a quick run through car wash out of habit since it only takes a few minutes to destroy..i mean...run the car through the tunnel. Not everyone working at a Dealership gets paid to really care or even think before acting and with large staff and a fast pace, communication gets easily lost on a daily basis.
i added "no tire shine" because when i got my last car, i specifically said multiple times " do not wash it" and they still sprayed their tire shine on there.
It will be done !!
