Thanks for posting the pictures of your tools, it's an area that I know zero about but would like to learn more.
We're similar in our approaches to painting cars, although I try to get as good as possible a finish from the gun, invariably there are sections that need polishing. With my Elan I have a good finish with reflections almost as good as yours (red doesn't have the same effect though), but that's because it's a small car and quite curvy, so the paint flows well. And with a small car it's easy to hand polish. I do a similar process to yourself, I used up to 1200 to get it matt & then cutting compounds - G3 paste, a fine "T-cut" grade and finally polish.
With the Europa and the large flat areas I have always needed to polish and I must admit, I get tired doing it by hand. The car is ok but I put enough paint on that I know it could be better, hence the question on tools. I've been hesitant and wary of burning through the paint, but what you're doing has convinced me to look again.
I can see you have an air tool but is the one at the back electric ? I prefer electric as my compressor is only 9cfm (and noisy) which is probably borderline for pro tools, so if you have any advice on what I should look for I'd be obliged.
