Dealer Detail Versus Professional Detail: What the Difference Is
This comes up constantly, usually when somebody has bought a car that looked immaculate on the lot and does not look that way a month later.
What a dealer prep is for
Making a vehicle look excellent for a viewing, quickly and at low cost. It is a legitimate job and it is done well by some dealers. But the objective is presentation on the day, and the methods reflect it.
Common characteristics:
- Fillers and glazes that mask swirl marks temporarily rather than removing them. They wash out over a few weeks and the defects reappear.
- Speed over process. A prep is measured in a couple of hours; a correction detail is measured in a day or more.
- Heavy dressings on plastics and tyres that look glossy immediately and attract dust.
- No decontamination, so bonded contamination remains under whatever was applied.
What a correction detail is
- Decontamination first — chemical, then clay — so the paint is actually clean before anything touches it.
- Machine polishing that removes defects rather than filling them, measured and checked as it goes.
- Protection applied to corrected paint, so what is preserved is the corrected finish.
- Interior extraction rather than surface wiping.
Why the price differs so much
Time, almost entirely. A proper correction on a neglected car is many hours of machine work by somebody who knows how to read paint. There is no shortcut that produces the same result.
When a prep is the right choice
If you are selling and want the car to present well, a good prep is exactly right and a full correction is money you will not recover. If you are keeping the car, correcting it once and then protecting it is the better spend.
