I consider claying a car an "extra". I charge $150 for a complete detail. What I consider a complete detail is...Hand wash. Machine apply my best wax. Remove by hand with microfiber. I vapor steam clean carpets, door panels, seats, mats, door jams, clean glass in and out, vacuum trunk, detail dash, console. Apply leather or vinyl treatment. Dress tires and clean rims. My price is very reasonable being a new mobile detailer. But I am trying to get a good client base. If the customer wanted the paint clayed, what should I charge for this above my Full detail? Dan
