There are lots of drying aid choices on the market. I like the idea of adding a fresh layer of wax after a wash to provide some additional protection on top of whatever you've got on the paint already. Wax generally doesn't do well if you have a coating, but this should look great with something like Collinite 845, most Polymer Sealants and, certainly Carnauba. You'll just have to try it and see.
This is what I think is important:
Yes you can use wax as a drying aid.
The look you get after application is better than any other product I've used as a drying aid. Griot's Spray Wax and Meguiar's D156 have always been my go-to products. This is much better (smells amazing too).
As far as I know, this is the only Spray Wax or drying aid that incorporates UV protection. This is a pretty chemically unique formulation.
I only offer this by the bottle for now.
In general, spray waxes require a bit more care to apply than something like Hydrate or Kenotech, but I think it's worth the effort. You just don't want to soak the whole car down with the product. You want to do one section at a time to make sure it doesn't dry.
While drying after a wash, I use to spot remove stubborn bugs.
Here is how I use it:
Blow the car off with a leaf blower.
Spray directly on damp or wet paint. Again, whether you use this as a drying aid or as a wax, I would strongly suggest you spray one panel or section at a time.
I use 2 of my Edgeless Drying Towels at a time, one in each hand. Essentially the first is the towels that spreads it. Follow with 2nd towel to remove remaining product.
