Talking about using QD after regular washing... when we use QD to boost the wax or add another layer of protection as a last step... sorry idol kung di clear
I did some research and it seems that it IS an actual practice... the mentioned that the QD lep removive friction from the drying towel when drying one's car...
here's the link to a forum I read...

here's some excerpts from OGE/OID found in autogeek:
Optimum suggests using the Optimum Instant Detailer & Gloss Enhancer in conjunction with Optimum No Rinse Wash & Shine. Use No Rinse as usual but, before you dry the vehicle, spray on some Optimum Instant Detailer. It will create a super slick, incredibly glossy finish.
After washing the car with Optimum Car Wash, spray your vehicle with Instant Detailer as you towel dry each panel. Optimum Instant Detailer & Gloss Enhancer can be used on wet or dry surfaces.
Mga Idol, what do you think of this practice? Parang sayang nga ung QD, plus, if the QD is hydrophobic (like Megs QD), I can't see how the QD will blend well with water...
