I am a big fan of Meguiar's products myself, however I use them only on my car except M16-wax.
Meg's polishes are quite good, but their current lineup is easier to use than the ones shown in the thread. For the classic products like M83, there were quite a lot of rules to follow in order to achieve a good finish.
Their current products are easier to use: Have a look at M105 and M205. M105 is called a compound, meaning that it is suited for paint with strong defects, and might leave micro-marring which can be removed with the much finer M205.
The main advantage of M205 and M105 is that there is no longer a need to work the stuff in until it gets clear. You can stop the polishing whenever you feel that the paint has reached the desired level of correction and just wipe the rest off with a towel and some IPA.
On clear coat, there is no real benefit in using a "glaze": A glaze is a chemical which is applied on polished paint to prepare it for the application of wax. It has some optical effect on classic one-stage paint, but it will not improve the appearance of clear-coat. However, glazes have no protective function and will not last on paint anyway, unless they are covered by a wax.
So, my suggested Meg's-products would be: M105 to level scratches or orange peel, and M205 to achieve maximum smoothness. You can cover the paint up with a wax afterwards to improve protection, but a glaze is not appropriate.
