The DJ lube is a QD, so you can just use that.
Spray wax is different than a QD, any product that claims to do both is lying and compromises on both. A QD is used as a lubricant, whether that's for clay or for a quick wipe over when or to get rid of bird crap (you'll mark the paint a bit, but that's better than a paint stain from acid poo!). A spray wax is IMHO a very cheap and poor substitute for a proper wax, although it's much easier to use.
Of course, I'm now going to totally contradict myself and mention things like DJ Red Mist, and the equivalent from Blackfire (both of which I use), which do add gloss and beading and can be used as a QD. Expensive way to do it though, and much better to have a cheaper separate QD. I use a 5L tub of the Megs Last Touch, cheap as chips and lasts for ages.
