Like Tim recommended, let it sit for some time to allow the paint to cure properly.
Purple Haze is a Dodo Juice product - very good stuff!

For your first wax, I'd say wash it with Dawn to strip off the original wax the body shop applied. Dry the car, then apply a sealant. I personally am a big fan of Blackfire products so I'd recommend their Wet Diamond.

After you're, done, wax it with a good Carnauba wax. With your color being a deep blue, I'd recommend staying with a Dodo Juice product, either with the Purple Haze they used or with their Blue Velvet. Dodo Juice makes a great product.

Yes, I know the products I provided links to are a bit on the pricey side, but you definitely get what you pay for. Believe me, I'd rather spend more on stuff that I'm confident will definitely protect a fresh paint job. Oh and in no way shape or form do I work for Detailed Image, they are just my go to shop for all my detailing needs and have been for years.
