I work 12 hour days, have a home to maintain and have a 4 year old daughter. But I find time to do it. It shouldnt take more than 4-5 hours unless you have some paint correction to do and/or depending how bad the paint is currently.
1.) Wash the car completely with a good shampoo, dry it off.
2.) Clay bar the whole car, re-wash, dry it off.
3.) Get a compounding pad, a DA and some compound of your choice.Compound the needed areas, if it doesnt need it, dont do it.(again, the stuff you use depends on how bad your paint is) See Seer's write up, its a good one)
4.) Hand polish the whole car. I like to do it by hand with some Meguiars polishing compound
5.) Get out the DA again, and use a finishing pad with a wax of your choice. If you drive the car alot, especially in the elements, you will want to throw 2-3 coats on, but that is debatable.
Check this thread out, its old, but it works. Obviously, what I just told you is no pro-detail by any stretch.
