it depends on what the car needs. Every car is defferent (color, condition, last time it was fully detailed, etc) However, just as a rough outline, this is what your average, decently maintained car probably needs:
1. Examine the car, make sure its relatively debris free, and look for any problem areas
2. Rinse first with a slow stream of water
3. Rinse with a slightly stronger blast of water to get everything you can off the surface
4. Wash
5. Rinse (sometimes a 2nd wash might be needed in extreme cases)
6. Dry
7. Clay
8. Remove swirls (DACP, SSR2, SSR1, SMR, etc)
9. Polish (PP, PWC, AIO, WGPE, etc)
10. Glaze/seal (VM, IHG, etc)
11. Wax/protect (S100, UPP, nattys, moose wax, etc)
12. Either do a light wash or QD to get all residue/dust off, i prefer to do a quick wash again.
These are simply steps for the paint. Most people start with the interior first. Some people do the wheels first, before the body. With me, its all a matter of what im in the mood for. Usually I want to jump right on the paint to start its transformation from dull to BLING because its the most fun (interiors are so boring and time consuming). And sometimes wheels can be a pain as well.
My full details start at $200 and take upwards of 5-6 hours.
