Painting 6 point roll bar inside the car

I'm having a 6 point roll bar installed in the 71 Dart. What have you guys done for paint in the past? Take the time to mask it off and rattle can? I've also heard of guys using a small roller and a foam brush?

Any photos of the finished product would be great! Thanks!
Any pics of the install points espically where hoop mounts to car? About to start on the 8point in my sons car .
