So I cleaned the roof of the camper today and tomorrow I'm using the dicor fiberglass roof sealant. I lifted up the shroud of the AC to clean around the unit and was wondering if I should put the dicor lap sealant around it. The front and the front half of the 2 sides of the AC are flush against the roof and the rest is about a half inch above. Is that were the condensate runs out? Could I just seal around the edges that are flush or is there a reason that it was not done originally? (Should I see the outside of the AC gasket?) Also - the roof is not a nice dome like it should be so I am concerned about water coming in. Thank you.
