Wash regularly from top to bottom. Drying is just as important. Use an electric leaf blower. Ideally as hard as it sounds you want to touch the paint as little as possible to avoid marring.
Use a quality drying towel of course. Use a quick detailer that has protection abilities within, this will make the paint a tad bit glossier and slicker wash after wash.
I'd suggest waxing again hen you notice the protection wearing off.
Car looks great, good job.
