Has anyone had a brown-colored stain splatter down from the forward hatch. I discovered this past weekeend in my H-27 (1990) a significant amount of splattering stains (fortunately it washed away with cleaner). It's not water coming in directly. It almost looks like a rust stain from within the edging inside of the hatch as if water has gotten up inside the edging. Has anybody experienced this and how to address it?
