Since I never caulk the roof before I have some questions! This is on a fiberglass roof, when I was at the factory I got some CSL Silicone caulk is that what I use, or do I want the self leveling kind...
Well, I just love YouTube. I did a little searching and found this video: Click here. Its hard to believe this was all done in only 7 minutes and 3 seconds!
Good stuff in the video. Maybe it will help you out.
