IPA is often used to strip any compound or polish residue that might be left behind during the correction process in order to confirm that defects are indeed being fully removed and not just covered up. This is usually done with a 25% solution or even higher in order to fully strip these oils. It may surprise you to find out that, yes, Ultimate Quik Detailer does have a bit of isopropyl alcohol in it - around 2%. It's in there simply to aid with drying of the product due to the polymer load it contains, but it's nowhere near enough to start removing wax. And if you've got a synthetic sealant on your paint, including things like NXT Tech Wax 2.0 or Ultimate Wax, UQD doesn't have anywhere near the IPA content to make a dent in it.

Now, as for using UQD and/or UQW immediately following a wash, we can see using one but not the other. UQD isn't meant to "last" in the sense that any wax or sealant will "last". It's there just to add lubricity to the surface to help you safely remove light dust or fingerprints. Yes, it does leave a bit of hydrophobic polymer on the surface, but that effect is very short lived. It is, after all, a quick detailer. If you've just washed your car, there isn't any dust on the surface to wipe off. If you want to use it to remove any light water spotting that might occur as water drips out from behind emblems, moldings, mirrors, etc, then fine - it works great for that. But if you want something to use all over the car as a matter of course immediately following a wash, then Ultimate Quik Wax is a much better choice.

UQW has surprisingly durable polymers that will indeed last for quite some time. For a spray on wax, the durability is actually fairly remarkable. It works great when used while actually drying the car. Do a final sheeting rinse where you take the nozzle off the hose and just a let a smooth, steady stream of water run over the paint to sheet off the majority of water beads, and then spray UQW onto a panel immediately before drying that panel. Use two folded Water Magnet waffle weave drying towels, one for the initial wipe and the other for a final wipe. You'll lay down a nice coat of polymer protection while you're drying the car.
