Duster window help

Second pic from the top... Raised places ? Hard to tell but... the fence that the gasket sits on is supposed to be flat and clean before butyl sealant is applied. The POR 15 really shouldn't be needed. I don't know for sure what I'm looking at and I don't know how thick the por crap is. All I know is the gasket sits on a fence and the fence does not / should not distort the gasket.
