Most chemists formulate their product to have a chemical synergistic compatibility, That is the chemist best knows how to make all the follow-up products in a system because they formulated the initial use or first step products in the system.
I'm not sure I've ever read any car wax manufacture recommend to chemically strip paint after using their products before going on to the next step.
But just to make sure everyone's clear, this is a
personal preference and no one will deny that Dana aka Asphalt Rocket is not good at what he does, so feel free to try his method but I want to point out in this thread for everyone that will read it into the future, that it's not recommended by the manufacture of the M105 and M205 to chemically strip the paint
and it's not necessary if you do a Test Spot first and insure that you're getting the results you''re looking for in your Test Spot.
Then the idea being if you're getting great results in your Test Spot, (which you can do an IPA wipe down to insure you're getting an accurate reading of your results), then there's no reason to wipe the entire car down if you're simply duplicating what you did in your test spot to the rest of the paint on the car.
Here's a thread that talks about chemically stripping the finish with lots of pictures that show why it's not necessary if you're using good technique to start with.

Here's a thread with a video that explains how and why to do a Test Spot before attempting to buff out your entire Mustang. This video uses a Flex 3401 but the principals apply no matter which tool you're using and even if you're working by hand.
