I am about to recoat my RV roof, and I want to cover all seals and joints with Eternabond tape as well. I see that several people had asked about applying the roof coating over the Eternabond that has already been applied, and how to do so. My question is, can I coat the roof first, then apply the Eternabond after the coating dries? That way I can save the step of sanding the Eternabond tape, and coating it with contact cement as recommended. Will this work?
