What detailing will and will not do
Nobody is served by a surprise on the day. Here is the honest version, before you spend anything.
It is not bodywork
Detailing works the clear coat and the surfaces. A dent stays a dent, a scratch you can catch a fingernail in has gone through the clear and needs paint, not polish. What detailing fixes is everything sitting on top of and inside that clear coat.
A coating is not armor
Ceramic makes the surface easier to clean and helps it shed water and road film. It does not make paint scratch proof, and any product sold on that promise is being oversold. It buys you easier maintenance and a longer gloss, not immunity.
Time is condition, not vehicle size
A well kept sedan can be quicker than a compact that has carried two dogs and a jobsite for four years. Anyone quoting a duration before seeing the car is quoting an average, and averages are how jobs run late.
Weather is a real constraint
Direct sun flashes products before they can be worked. Hard wind puts grit back on wet paint. Freezing temperatures change what will cure at all. Covered parking widens the calendar considerably in a Nebraska and Iowa winter.
Interiors have a ceiling
Shampoo and extraction pull a great deal out of carpet and fabric, including odor that lives in the padding. Permanent dye stains, burns and torn material are a different trade. You will be told which one you have before work starts.
Maintenance beats rescue
The most expensive detail is always the one that follows several years of automatic car washes. Keeping a finished car on a regular wash schedule costs far less over time than correcting it back every few years.
