Quik Detail is not necessarily made for after a wash. If you wash and dry your car properly (meaning removing all the dirt and not leaving water spots), a "QD" is not needed. A QD is used primarily for between washes to remove dust, fingerprints, bird bombs, etc. A few do contain shine enhancers as well, such as Meguiars Final Detail (replaced by their new Last Touch). But they do not leave any protection
per se on the paint. BTW, Final Detail is an awesome product I use almost daily.
For spray waxes, they do have their place in my detailing arsenal, but are not an absolute substitute for full blown waxes/sealants. They are for the times in between wax jobs that you want a freshly waxed appearance. Or to "rejuvenate" your existing wax. They offer limited protection, but do enhance gloss and slickness. I use Eagle One Wax As U Dry or Meguiar's NXT Spray Wax. The Eagle One WAUD is ridiculously easy to use. I only use one squirt per wet body panel, and dry with a waffle weave microfiber I got at
www.exceldetail.com. It's literally that easy. No buffing or waiting for it to haze. And it does add a nice gloss and slickness. The NXT Spray Wax I use on a clean, dry surface. It is basically a liquified wax that you spray
LIGHTLY, spread
THINLY, wait for it to haze (which is quick), and buff off. It is slightly faster than the full blown NXT Wax, which itself is easy to use. The Spray Wax adds a good gloss and I think incredible slickness. It also seems to keep these attributes for slightly longer than WAUD. But it is not as easy or quick as WAUD. As for using a spray wax as a quick detailer (to touch up a dirty or dusty car), I would never do it. Spray waxes are designed to be used on
CLEAN cars to give limited protection and a freshly waxed appearance. They do not contain lubricants like QD's do to prevent dirt or dust from being ground in to the surface as you wipe it off. Using a spray wax as a QD is a sure way to scratch or mar the paint surface.
An excellent resource for detailing information is
www.autopia.org. The forums there are full of professional and enthusiast detailers who are a gold-mine of detailing information. Not to mention reps from companies such as Meguiars and Mothers. But like any other forum, there are a few members who know just enough to give improper information at times. The
LEARN icon at the top of the web page is a good starting point to learn the basics of proper detailing. They also have a good search function, where the answer to almost any detailing question can be found. There is also a lot of vendor information so you can get good quality products and tools to take your car's appearance to its full potential.
Hope this helps.
