I¡¯d say use whatever method solves your problem. There is a benefit in making sure grounds from connectors are touching the metal case and why not have all the case pieces bonded, it just helps all around. I have the black case with 5¡± screen. The paint is thick but scraping real good does get it off. I used a file at times and my dremel. Trying to scratch with a flat screwdriver was tricky. It really a no brainer if your starting the build. But I had everything already assembled before I thought to remove the paint. Not ideal.
Btw I live in a house made of wood and sheetrock. My cell service indoors is horrible as well.

Re Faraday cage. I live in a steel sided and roofed house the panels are not bonded together but yet no cell phone service inside. That was not my question.
When I first got a radio going had rf on the mic. The solution for me was to put an rf choke at the antenna hub. You might consider that solution rather than trying to fight it in the radio.
The finish can be removed pretty easy, too easy from my perspective. Around the case holes it has chipped off on it's own. It looks like powder coating.
