I have two bottles in my trunk. They both say they clean, shine, and protect the paint. They both instruct the user to spray, wipe with a clean MF, then dry with the flip side. They both warn against use on heavily soiled cars. They both do a good job of making the car look good.

What's the difference?

QD is for light dusting... finishing touches if you will
WW is actually a car wash but should be limited to moderately dirty cars.

I never use a QD.
there's no point in fine touch ups. either your car is clean or it has a light dust to it.
if going through all that trouble just to "quickly touch it up" you might as well do a full wash

I agree.
Especially with spray waxes and rw/ww.... QD is going down the same road as the dinosaurs.

Only time I use QD is when I clay... even then, some rw/ww concentrates can be diluted to be used as clay lube.

I sometimes use QD after washing the car.

for?

Once you run out of your QD, you should try spray waxes instead. It not only gives your car a freshly waxed look and feel, it also gives you a layer of protection.

The Mequiars QD brings up the shine in between waxing I find. Probably doesn't last long but the finish is smoother and shiny when I do it.

Also QD is good for keeping the lubrication alive while drying the car if there's its gotten dried up.

What everyone said plus, quick detailer is great for getting off dried wax or fresh bird poop or stuff that get's on. I use QD on the glass for a streakless finish.

Spray wax is great for washes after having used sealant or wax. Extends the life of wax and makes the car look great.

Typically I wash using a microfiber wash mitt, hose off any excess suds, dry using a high pile microfiber towel, good to invest in a couple of those, then use spray wax for a final wipe down to replenish the wax already on the car.

The paint has some marring from use over the years but looks brand new when everything is layered on.

Also you can make your own "safe to wipe QD" using waterless wash liquid. I use optimum no rinse in a chemically resistant spray bottle. No more spending $'s for QD.

use a different wax.

QD's are a waste of time and money. unless you make your own like Disturbed mentioned

I use Autoglym HD and a cheaper orbital polisher which works well for me but I only wax with the Autoglym HD 2 or 3 times a year.

As I also claybar a couple of times a year I like to have QD handy for claybarring. I grab a few bottles when on sale so it is not that big an expense and as I said the QD works fine for me. To each his own.

I'll use a QD usually just on the rear panels after I have driven to a car show just to remove very fine dust or brake dust. If any more than that I use ONR to clean the areas.

i totally hate when my TL buddies come over to meet up before a meet.
they use QD on a dirty car!!!!!!!

my car will stay dirty until I have the proper time to clean it, meet or not.
