So, I noticed that KZ totally cheaped out on the front roof-to-cap seam on my '17 Durango 1500. Silicon bead along the seam, covered by a 1+" wide seam of Dicor, EXCEPT for a gap of 3-4" at each end,...
I've used nothing but self leveling Dicor on my 32' trailers roof. No problems in 21 years. If you use the sticky tape follow instruction especially when your laying it over silicon or piled up lap sealant. Then once you get it down right add Dicor around the edges to seal out water like the pros do it. Just be aware the trailer mfg may void your roof warranty....if it still in effect.
