so if you apply it heavier in some areas then others those parts will be darker then the other areas and how well does this work with UQD?In all honesty, we haven't played with it as a trim dressing and it isn't really intended for that even though it won't stain trim. We fully expect some people to experiment with it, some with excellent results and others with less so, but that's what happens when using a product in a way other than designed.
Dry time is similar to that of NXT, maybe a bit less. It can still appear to be a bit wet but it will wipe off with ease even then. The polymer load is such that the swipe test may not be 100% accurate here - give it a good 20 minutes or so before wipe off.
Here's a little tip at wipe off: if you find any visual unevenness after wiping it off (slightly darker patches due to inconsistencies in thickness of application) then very light spray some plain water onto a clean, dry microfiber towel and wipe the car down as a quick follow up. And by "very lightly spray" we mean exactly that. In fact, spraying a mist in the air and catching it with the towel is sufficient. Definitely don't over do it here. What happens is the polymers are still quite dynamic on the surface immediately after wipe off, and it they aren't pretty evenly distributed you may see some slightly darker patches because of it. That very lightly damp microfiber helps to shift things around, evening out the layer.
We hesitate to even mention this but we know some of you MOL folks are extremely particular about how things perform and you tend to notice very minute details. As you might imagine, if the above does happen it's going to be most noticeable on darker non metallic colors and under certain lighting or viewing angles. But the polymers are easily spread and the final result is fantastic!
Personally speaking, I'd say it's still more of the sealant wet glass look, but the darkening prevents that from being the sort of shine that has been (not kindly) described as "wrapped in Saran Wrap" plastic-y.
