Personal experience is that those wash and wax products are useless. Assuming that you don't want to bother with all the steps and just want to simply wash and wax, I would suggest using Klasse All-In-One. It is a cleaner wax that is basically a paint sealant, chemical paint cleaner, and non abrasive polish all in one, hence the name. It is a wipe on wipe off product so you don't have to wait for it to cure. Just wipe in on then wipe it off, I can do a whole SUV with it in about 20 minutes. Once your done you are good to go for around 3-4 months. It is a little bit pricey but even a 10oz bottle should last you years. Another really great easy to use wipe on wipe off product is Meguairs Ultimate Fast Finish, however this one works best of paint that has been washed and clayed.
