If you are ok with diy it is possible. As DaveW says leave metallics to the pros.
I have done small jobs on my cars using either aerosol cans or airbrush, even wet flatting with very fine wet and dry. Did a small ding on my 4/4 like that. Airbrushed paint and pleased with the result.Luckily my dad was a coachbuilder and I used to work school hols with him.
People like Chipsaway etc use airbrushes to paint after the obligatory high level of prep, rubbing down etc. They now use water based paints and infrared heaters to speed up drying. They can also do bigger areas by using larger sprayguns.
Same for dent removal by pros. The good ones are impressive!
From your escription of the problem you will need to be meticulous in prepping to properly get rid of the bubbles and the cause of them. I am guessing that wet and dry rubbing back to bare metal is needed. Look at you tube videos to see the process. Experiment on something like a scrap panel, a metal toolbox, tin can.....anything with curves! ( behave yourselves) if you are then happy give it a try. At worst you can get a pro to re-do it?
Having been to a Chipsaway demo day when I was contemplating taking a franchise the smart repair route is good. Cheaper than a bodyshop and done in a couple of hours. It is worth checking examples or photos of work done too, most will take some to show prospective clients.
