The most I've ever had to pay someone to wash and wax ours was $300.
It was so clean and slick, it made it easy to pay him.
To get it that slick enough to be worth $1800 you would fall out the door.
I've been fixing cars (autobody) for over 20 years. I specialize in paintless dent repair, I worked with 100's of dealers around the country. They pay their wash guy $10 to wash cars, then when somebody buys the sealant he has to use a spray wax after.
Each place uses a different spray wax, generally which ever is the cheapest to buy at the time.

It's your $1800, how long do you think it would take you wax it?
