However you do it... it's important to have controls in place. It's not always easy coming up with perfect controls.
I've done comparative testing before and there's two general ways to do it...
I'd opt for the super simple method otherwise you can go so deep that you can never get out, by this I mean never finish the testing and publishing your findings. Just find a way to keep it simple, wash and rinse one of our cars and then take one brand of towel and dry it off. Have someone there to take notes. Notes are you monitoring what you're seeing and experiencing.
Summarize and publish.
The thing about doing this testing on cars sealed with wax or sealant is the more you wash and dry the cars the more you'll micro-abrade off the wax or sealant. With a ceramic coated car, the ceramic coating is a lot less likely to wear off from careful washing and drying and thus a coated car would be a better "control" to test the performance of removing water versus a waxed or sealed car.
Just my thoughts after spending about 3 minutes thinking about how I would do comparative testing.
But for sure... keeping it simple will probably work better than making it complicated. At the end of the day, all we all want to do is get the water off our cars without scratching the paint and wasting time.
Good luck!
