VanleighRe-sealing the nose of a fifth wheel

Eterna bond recommends a coating over it. I don't like the crappy way the mfgrs seal things... by caulking OVER edges AFTER things are screwed down. I removed all screws and cleaned under the overlaps, caulked, and then shot the screws back in. Then eternabond and roof coating over everything on the roof.
It took the first 5 months of 2019 and I did ALL the other lap joint on my 5er, windows, roof lights and fans and bottom skirting, by cleaning and caulking under every joint. I dare anything to leak! Craig
