What do you guys think about using rubbing compound-->touchup paint-->polisher to finish?
If you're not a very experienced artist with touch-up paint you're just messing up your $100,000 super car.
As someone who has owned and had a string of "delicate" automobiles and seen a lot of body work over the years - and as someone who has a detailer at his house every week washing his cars - my advice to you is to not be penny wise and pound foolish.
I assume if you can afford this car you make a lot more per hour than an experienced detailer/paint guy.
So go do another consult, case, bill an extra hour, raise the rent on a tenant - whatever you got to do. And then pay a professional who knows what he's doing with an orbital and a paint brush, and can actually blend touch-up paint correctly followed by a spot color sand.
Doing touch-up paint so that it actually blends with the paint is incredibly time consuming and involves many coats because touch-up paint shrinks. So you lay down one coat, let dry. Lay another, let dry. Etc. etc. etc until you get the paint to dry above the surface of the surrounding paint.
Now you have to color sand your touch up paint so that it blends with the surrounding paint.
Then finally you have to try to spot clear coat on top and color sand/blend the clear spot.
If you just pay an expert to do it you will still save a lot of money over getting the panel repainted, but you will get the technique of someone who knows what they are doing with polishing compound and power tools because they do it all day long.
In all seriousness if those scratches are really deep and you go to work with something strong enough to do the job you will likely burn through your paint as a noob.
You could pay maybe $100 to an experienced detailer who does a lot of paint correction work (search forums like ferrarichat.com's Massachusetts sub-forum - there is little expertise on this forum in the care of high dollar paint jobs because this isn't a typical high dollar car crowd) to work on that panel.
If it won't buff out at least you know you tried.
