I would not. Why take the chance? It doesn't have to rain for the car to accumulate gritty dirt on it. A good detailer will tell you to NEVER wipe down a car with just a towel after driving it.
The only time I would just use a towel is if Its been freshly detailed and sits in the garage over night without it going ANYWHERE.
The premium "made for dark colored car waxes" IMO do give a bit of a darkening effect/look to it but you really don't need them to make your ride look good.
This is going to be a bad machine. 2015 Chevy Corvette Z06 is most powerful production GM car ever with 650 hp, 650 lb-ft - Autoblog The dynograph is pretty wicked. 650lb/tq @ 3600rpm
Looks good Gerry. I also had the same results on my wheels with QS. 2 Coats lasted 3 months in the harsh winter we had recently (would've lasted longer but I stripped it and applied something else) It was then that Quick Sealant really made me a believer.
There is one thing I like about the Waterless Wash, it is that to my understanding it does not contain wax/gloss enhancers whereas the Rinseless wash does. I prefer NOT to have gloss enhancers or any additional fillers.
