I'm a total newbie so keep that in mind. I'm quickly coming to the opinion that a lot of harm is done washing the car. Using something like a normal bath towel to dry your car afterwards can scratch the you-know-what out of it.
Slow down, take your time, and ask a lot of questions. Carefully make up your order and buy the right stuff all at once (to save on shipping). For the most part, it is hard to buy quality stuff over the counter at a local place.
I'm amazed at the things I notice now that I never did before. The right lighting is important to. You can think you have something looking great only to see it in another lighting condition and find out otherwise. Do the "test spot" thing. Get the paint right before you waste time and money on a sealant/protectant/wax.
Pretty much everyone will agree on the first couple/few steps. Wash & dry, IronX, clay bar. From there your ability to carefully inspect, along with what you wish to accomplish, will determine the next steps. You might decide you want all the defects out and need to compound/polish/glaze. Or you might decide it is a daily driver and it looks fine to you. In that case a product the polishes/cleans/hides and protects might be all you need. That is pretty much what all the waxes from the old days were.
There are way too many choices out there for a new guy to make a good choice without doing a lot of homework. I know you are itching to go but remember it is very easy to do more harm than good. In a month or two you will be telling people not to go near any auto detailer that charges less then a couple/few hundred....and whatever they do don't let the dealership ever wash their car....LOL!
