Here we've taped-off the rubber gasket between the glass and the window frame and I'm pointing to show that there's about an 1/8th of an inch of paint that's not going to get buffed with either of the two polishing steps.
After the correction steps we'll remove the tape and carefully wax these areas for a uniform look that will match the polished areas next to the tape line.
While not
perfectionist detailing in some eyes, remember this is a daily driver, not a show car.
You can invest more time and just run the tape down the rubber and get it close to the edge of the panel if you want or just overhang a little like I did here. It's your choice based upon what you're trying to accomplish and how much time you want to invest.
