Good tip on sealing the edges of the tape with Dicor!

I did not do that, but I did think of it, but I wasn't sure if that would work if the self-leveling Dicor would just run down the side of the RV.

I think Dicor might make both a self-leveling and a non self-leveling product (more like caulk?).

Is there a Dicor product you are specifically referring?

EDIT: I see that Dicor makes a non-sag non-leveling product. I haven't used their products before, so not sure which color to get to match the roof. White or Dove Gray? If the Dicor color will match the roof color better than the Eternabond tape, I'll just use a spreader and cover over the tape as well.
