What is it that you are looking for from using a QD? Are you wanting to give your paint an extra "pop" or do you want to use a QD for the purpose of maintenance in between washes?
There are basically two different types of QDs, and you should know which type you are buying. There are QDs that are meant to be used on a clean paint surface only, and there are QDs that can be used on dirty paint surfaces.
QDs are not all created equal, however in general they definitely do really work. They can elevate the shine of your paint, reduce the amount of dust, pollen, etc that sticks to your paint, allow you to remove smudges, fingerprints, etc as well. And most importantly, they extend the life of whatever paint protection you are using. If you are using a QD like Poorboys Spray & Wipe, it will allow you to remove light dirt, dust, pollen, bird bombs, etc. This type of QD can be used on a dirty paint surface because it has lubricants in it that prevent you from scratching your paint surface. They drastically reduce the number of times you need to wash your car as you can perform quick and easy maintenance between full washes.
My main QD is Poorboys Spray & Wipe. I keep a bottle of this in each of my vehicles at all times and never leave home without it. I also use Menzerna Top Inspection, Chemical Guys Extreme Slick Synthetic, and Zaino Z6. The Menzerna and Zaino QDs are for clean paint surfaces only.
So yes, QDs really do work!
