Resealing the Edge of the Roof, Dicor, Eternabond, or Both?

I elected to use Eternabond along all the edges in my Class C many years ago - my 91 is still leak free. When you apply eternabond pay attention to the "prep" work as it requires a clean surface to properly bond. You should remove the loose caulk ... if you elected to remove all the caulk (not mandatory) I would recommend that you use an oscillating tool with a special caulk remover blade (rounded flexible blade that isn't sharp and won't harm roof membrane).
