I wouldn't bother waxing it. As said, there's so much dust about at the moment you're wasting your time and effort imo. If you've sealed it that should be enough until the next wash. But next time make sure to wax it as well.
I disagree. Wash &dry it again then wax it mate.
The wax will help protect the paint over the top of the sealant & should with the glossiness of the finish.
Agree with spacemonkey, I wax my car every time I wash it. It's never wasted to wax a car in my opinion...
The 100£ you waste on waxing a car in your car's lifetime, are equal to 200£ profit, selling it with high gloss paint, even if 10y old.
I live near the coast (salt, sand, dust, wind, rain...) so waxing is a 'must-do' around here, don't forget to wax the chassis (bottom of the car) to prevent rust!
