As others have said, depends on your area, and how much competition you have. If I lived 50 miles west of me, I could probably do coatings all day (wealthy people) And I could charge much more than I do. Where I live though, lots of cheapskates and 2 person detail teams in plain white vans who will "wash" your car for $15. I see one of these vans at a strip mall around the corner every day. I bet they do 25 cars a day. After expenses they probably make around $150 each a day, not good for non stop out door work. It also doesn't help that 70% of people I talk to about me being a detailer think a "full detail" is a wash + wax + vacuum. And it better be $40'ish 50 max.
My rates for what you asked:
Wheels & Tires - I have 2 packages, a basic one, and one where I use an Iron remover and a tire coating that lasts 2-3 months.
Basic - $30
Upgraded - $60
Wash (waterless with AMMO Frothe)
$30 for a compact car
$35 for a sedan.
$45 for a truck, SUV or Minivan.
Clay - Nanoskin Autoscrub $60
Spray Sealant (no express wax) $60 - Lasts 6'ish months.
I have 3 packages, and my Al La Carte menu has 24 items. A couple are duplicates depending on the vehicle size. If someone wants strictly Al La Carte, I have a $35 minimum, and if they get 3+ things it's 10% off, 5+ 15% off.
I just started last week, so my prices aren't set in stone. My town's full of quick, cheap, good enough where it looks clean van dudes. So I can't compete with them on pricing or speed, a lot work in pairs. And even the solo ones just bang thru, where I don't rush. Since I'm mobile only, if I have to travel over 5 miles, I charge a buck a mile. I'd say for the products I use, and the attention I give the cars my prices are a bit low. But as other have mentioned in a lot of parts of the country I couldn't even charge what I do.
