Sorry, our username is confusing.... several of us post under the same account name.
My name is actually Zach. I work for Detailed Image as a support to the various forums they sponsor and also as an author for their

Now on to your question... Your process seems great!
Wash, decontaminate, correct, polish, protect. That is the basics of a good exterior detail.
Higher end waxes tend to use more expensive ingredients and are produced in smaller batches, which results in higher product costs. A true wax addict may be able to point out subtle differences in appearance between various waxes, but the majority of us won't necessarily be able to distinguish a $100 wax from a $500 wax. My personal favorite carnauba is
Pinnacle Souveran paste wax... but you also can't go wrong with something like
Pete's 53 either! There are so many choices, you can have a lot of fun experimenting with them
Hope that helps, let me know if you have any other questions.
