While checking the vent for the stinky problem(by the way the picture is in the album) noticed that maybe I should seal or reseal a couple vents. I see this appears be the self leveling type(fiberglass roof) by I have no leaks now and have just some cracking in the seal. Seems to be just a surface crack on one side of 3 vents. Should I remove all the seal(as the other 3 sides look good) or just the one side or just ruff up the cracked area and seal over that area. Also what brand of seal and where to get it. Also what is the best way to remove the old seal material.
