To those who have painted their roof, question.

[Gauge]

So I'm getting my roof painted at a shop next week. I took it in for them to check out the roof. To make it a clean edge they are going to open the trunk while painting the back section, so they can get deeper down in the back seam for painting. The front is the front, not much to fuss about there.

My real question is the driver and passenger side. There is a rubber seal there. Their plan is to mask just barely over the seal to make the paint go into the rubber seal so you won't see any original paint color. Something about this doesn't seem right to me. If the rubber shrinks or something paint will become visible.

When you guys got your roof painted how did it go? Where did they mask? If you did the above, does it still look good after a long period of time.
