Either way, you're better off putting down SOME kind of true wax/sealant base over the paint first, before you use the UQW. I frequently use Meguiars NXT 2.0 Paste Wax as my base. Its durability is not the best, but the UQW helps me easily get 6 months out of it, since I use it after every wash.
Thanks for this information.
What if I already applied the UQW as a base and now I want to apply the Megs Ultimate Paste Wax?
Can I apply UPW over the UQW?
This would not really be of any benefit. The Ultimate Paste Wax contains solvents that would most likely just strip what protection the UQW has left. You'd end up with a good coat of UPW. The UQW essentially acts as a topper - repeatedly rebuilding the protection that regular washes, rain, and other elemental factors remove over the course of time.
