No, I lipped over onto the metal trim that meets the roof with the primer and Liquid roof about 1/4" to 1/2". Used blue painters tape. The trick is knowing when to pull it off.
You want to do it while it's still somewhat wet. Otherwise the rubber sets up and you will be using a razor blade which is what I had to do . If I did it again I would not put the liquid roof on the curved sides as heavy as I did and then I would be able to pull the tape off sooner and not have to worry about sagging. If you think about it the liquid roof doesn't have to be really thick on those curved sides as the water will just run right off anyway. It's more important to have it thicker on top of the roof. I have some slight sagging that dried and it doesn't look that great. That stuff self levels really well so if I would've just put it on thinner it would look great from down below. It fills the gap between the rubber roof and the metal molding nicely. I think Eternabond tape there would be a total overkill and wouldn't look very good. However I think I'm going to go back up this week and use Eternabond tape around my shower skylight, refrigerator vent.
