I agree with that Mirror, you definitely can make more doing it that way, however, I ran into a problem with it. I detailed a car a year ago and charged X amount of $$ and said after your maintenance, I`ll see you in 6-9 months. I might have made the mistake of saying that the first detail is usualy the dirtiest, and the second will have less steps. I think they caught on that they would be charged the same price for less service. On the flip side, you could substitute a polishing step for a glazing step or a final topper step I guess.

When it comes down to it, I always find myself making less $$ on the dirty ones, just because it takes more time to do, but LESS money is better than NO money.
